Upgrade Instructions for 4.3¶
This section contains upgrade instructions from prior versions of CloudStack to Apache CloudStack 4.3. We include instructions on upgrading to Apache CloudStack from pre-Apache versions of Citrix CloudStack (last version prior to Apache is 3.0.2) and from the releases made while CloudStack was in the Apache Incubator.
If you run into any issues during upgrades, please feel free to ask questions on users@cloudstack.apache.org or dev@cloudstack.apache.org.
Validate 4.3 source code tarball¶
Perform the following to verify the artifacts:
(optional) Install GPG keys if needed:
$ sudo apt-get install gpg
Import the GPG keys stored in the source distribution’s KEYS file
$ gpg --import KEYS
Alternatively, download the signing keys, the IDs found in the KEYS file, individually by using a keyserver.
For example:
$ gpg --recv-keys CC56CEA8
Get files, refer to CloudStack Download Archive Page for source package download.
$ wget http://archive.apache.org/dist/cloudstack/releases/4.3.1/apache-cloudstack-4.3.1-src.tar.bz2 $ wget http://archive.apache.org/dist/cloudstack/releases/4.3.1/apache-cloudstack-4.3.1-src.tar.bz2.asc $ wget http://archive.apache.org/dist/cloudstack/releases/4.3.1/apache-cloudstack-4.3.1-src.tar.bz2.md5
Verify signatures and hash files:
$ gpg --verify apache-cloudstack-4.3.1-src.tar.bz2.asc $ gpg --print-md MD5 apache-cloudstack-4.3.1-src.tar.bz2 | diff - apache-cloudstack-4.3.1-src.tar.bz2.md5 $ gpg --print-md SHA512 apache-cloudstack-4.3.1-src.tar.bz2 | diff - apache-cloudstack-4.3.1-src.tar.bz2.sha
Each of these commands should return no output. Any output from them implies that there is a difference between the hash you generated locally and the hash that has been pulled from the server.
Get the commit hash from the VOTE email.
For example:
4cd60f3d1683a3445c3248f48ae064fb573db2a1
. The value changes between releases.Create two new temporary directories:
$ mkdir /tmp/cloudstack/git $ mkdir /tmp/cloudstack/tree
Check out the 4.3 branch:
$ git clone https://git-wip-us.apache.org/repos/asf/cloudstack.git /tmp/cloudstack/git $ cd /tmp/cloudstack/git $ git archive --format=tar --prefix=/tmp/cloudstack/tree/ <commit-hash> | tar Pxf -
Unpack the release artifact:
$ cd /tmp/cloudstack $ tar xvfj apache-cloudstack-4.3-src.tar.bz2
Compare the contents of the release artifact with the contents pulled from the repo:
$ diff -r /tmp/cloudstack/apache-cloudstack-4.3-src /tmp/cloudstack/tree
Ensure that content is the same.
Verify the Code License Headers:
$ cd /tmp/cloudstack/apache-cloudstack-4.3-src $ mvn --projects='org.apache.cloudstack:cloudstack' org.apache.rat:apache-rat-plugin:0.8:check
The build fails if any non-compliant files are present that are not specifically excluded from the ASF license header requirement. You can optionally review the target/rat.txt file after the run completes. Passing the build implies that RAT certifies that the files are compliant and this test is passed.
Upgrade from 4.3.1 to 4.3.2¶
This section will guide you from CloudStack 4.3.1 to CloudStack 4.3.2.
Any steps that are hypervisor-specific will be called out with a note.
We recommend reading through this section once or twice before beginning your upgrade procedure, and working through it on a test system before working on a production system.
注釈
The following upgrade instructions should be performed regardless of hypervisor type.
Most users of CloudStack manage the installation and upgrades of CloudStack with one of Linux’s predominant package systems, RPM or APT. This guide assumes you’ll be using RPM and Yum (for Red Hat Enterprise Linux or CentOS), or APT and Debian packages (for Ubuntu).
Create RPM or Debian packages (as appropriate) and a repository from the 4.3 source, or check the Apache CloudStack downloads page at http://cloudstack.apache.org/downloads.html for package repositories supplied by community members.
Instructions for creating packages from the CloudStack source are in the CloudStack Installation Guide.
Stop your management server or servers. Run this on all management server hosts:
$ sudo service cloudstack-management stop
If you are running a usage server or usage servers, stop those as well:
$ sudo service cloudstack-usage stop
Make a backup of your MySQL database. If you run into any issues or need to roll back the upgrade, this will assist in debugging or restoring your existing environment. You’ll be prompted for your password.
$ mysqldump -u root -p cloud > cloudstack-backup.sql $ mysqldump -u root -p cloud_usage > cloud_usage-backup.sql
(KVM Only) If primary storage of type local storage is in use, the path for this storage needs to be verified to ensure it passes new validation. Check local storage by querying the cloud.storage_pool table:
$ mysql -u cloud -p -e "select id,name,path from cloud.storage_pool where pool_type='Filesystem'"
If local storage paths are found to have a trailing forward slash, remove it:
$ mysql -u cloud -p -e 'update cloud.storage_pool set path="/var/lib/libvirt/images" where path="/var/lib/libvirt/images/"';
If you are using Ubuntu, follow this procedure to upgrade your packages. If not, skip to step upgrade-rpm-packages-4.3.
注釈
Community Packages: This section assumes you’re using the community supplied packages for CloudStack. If you’ve created your own packages and APT repository, substitute your own URL for the ones used in these examples.
Now update your apt package list:
$ sudo apt-get update
Now that you have the repository configured, it’s time to upgrade the
cloudstack-management
package.$ sudo apt-get upgrade cloudstack-management $ sudo apt-get upgrade cloudstack-usage
Now it’s time to start the management server
$ sudo service cloudstack-management start
If you use it, start the usage server
$ sudo service cloudstack-usage start
(VMware only) Additional steps are required for each VMware cluster. These steps will not affect running guests in the cloud. These steps are required only for clouds using VMware clusters:
Stop the Management Server:
$ sudo service cloudstack-management stop
Generate the encrypted equivalent of your vCenter password:
$ java -classpath /usr/share/cloudstack-common/lib/jasypt-1.9.0.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI encrypt.sh input="_your_vCenter_password_" password="`cat /etc/cloudstack/management/key`" verbose=false
Store the output from this step, we need to add this in cluster_details table and vmware_data_center tables in place of the plain text password
Find the ID of the row of cluster_details table that you have to update:
$ mysql -u <username> -p<password>
select * from cloud.cluster_details;
Update the plain text password with the encrypted one
update cloud.cluster_details set value = '_ciphertext_from_step_1_' where id = _id_from_step_2_;
Confirm that the table is updated:
select * from cloud.cluster_details;
Find the ID of the correct row of vmware_data_center that you want to update
select * from cloud.vmware_data_center;
update the plain text password with the encrypted one:
update cloud.vmware_data_center set password = '_ciphertext_from_step_1_' where id = _id_from_step_5_;
Confirm that the table is updated:
select * from cloud.vmware_data_center;
Start the CloudStack Management server
$ sudo service cloudstack-management start
(KVM only) Additional steps are required for each KVM host. These steps will not affect running guests in the cloud. These steps are required only for clouds using KVM as hosts and only on the KVM hosts.
Configure the CloudStack apt repository as detailed above.
Stop the running agent.
$ sudo service cloudstack-agent stop
Update the agent software.
$ sudo apt-get update cloudstack-agent
Verify that the file
/etc/cloudstack/agent/environment.properties
has a line that reads:paths.script=/usr/share/cloudstack-common
If not, add the line.
Start the agent.
$ sudo service cloudstack-agent start
If you are using CentOS or RHEL, follow this procedure to upgrade your packages. If not, skip to step restart-system-vms-4.3.

Community Packages: This section assumes you’re using the community supplied packages for CloudStack. If you’ve created your own packages and APT repository, substitute your own URL for the ones used in these examples.
The first order of business will be to change the sources list for each system with CloudStack packages. This means all management servers, and any hosts that have the KVM agent. (No changes should be necessary for hosts that are running VMware or Xen.)
Start by opening
/etc/apt/sources.list.d/cloudstack.list
on any systems that have CloudStack packages installed.This file should have one line, which contains:
deb http://cloudstack.apt-get.eu/ubuntu precise 4.2
We’ll change it to point to the new package repository:
deb http://cloudstack.apt-get.eu/ubuntu precise 4.3
If you’re using your own package repository, change this line to read as appropriate for your 4.3 repository.
Now update your apt package list:
$ sudo apt-get update
Now that you have the repository configured, it’s time to upgrade the
cloudstack-management
package.$ sudo apt-get upgrade cloudstack-management

注釈
Community Packages: This section assumes you’re using the community supplied packages for CloudStack. If you’ve created your own packages and yum repository, substitute your own URL for the ones used in these examples.
The first order of business will be to change the yum repository for each system with CloudStack packages. This means all management servers, and any hosts that have the KVM agent.
(No changes should be necessary for hosts that are running VMware or Xen.)
Start by opening
/etc/yum.repos.d/cloudstack.repo
on any systems that have CloudStack packages installed.This file should have content similar to the following:
[apache-cloudstack] name=Apache CloudStack baseurl=http://cloudstack.apt-get.eu/rhel/4.2/ enabled=1 gpgcheck=0
If you are using the community provided package repository, change the base url to http://cloudstack.apt-get.eu/rhel/4.3/
If you’re using your own package repository, change this line to read as appropriate for your 4.3 repository.
Now that you have the repository configured, it’s time to install the
cloudstack-management
package by upgrading the oldercloudstack-management
package.$ sudo yum upgrade cloudstack-management
Now it’s time to restart the management server
$ sudo service cloudstack-management start
For KVM hosts, upgrade the
cloudstack-agent
package$ sudo yum upgrade cloudstack-agent
Verify that the file
/etc/cloudstack/agent/environment.properties
has a line that reads:paths.script=/usr/share/cloudstack-common
If not, add the line.
Restart the agent:
$ sudo service cloudstack-agent stop $ sudo killall jsvc $ sudo service cloudstack-agent start
Now it’s time to restart the management server
$ sudo service cloudstack-management start
Once you’ve upgraded the packages on your management servers, you’ll need to restart the system VMs. Ensure that the admin port is set to 8096 by using the “integration.api.port” global parameter. This port is used by the cloud-sysvmadm script at the end of the upgrade procedure. For information about how to set this parameter, see “Setting Global Configuration Parameters” in the Installation Guide. Changing this parameter will require management server restart. Also make sure port 8096 is open in your local host firewall to do this.
There is a script that will do this for you, all you need to do is run the script and supply the IP address for your MySQL instance and your MySQL credentials:
# nohup cloudstack-sysvmadm -d IP address -u cloud -p -a > sysvm.log 2>&1 &
You can monitor the log for progress. The process of restarting the system VMs can take an hour or more.
# tail -f sysvm.log
The output to
sysvm.log
will look something like this:Stopping and starting 1 secondary storage vm(s)... Done stopping and starting secondary storage vm(s) Stopping and starting 1 console proxy vm(s)... Done stopping and starting console proxy vm(s). Stopping and starting 4 running routing vm(s)... Done restarting router(s).

/etc/apt/sources.list.d/cloudstack.list
on any systems that have CloudStack packages installed.This file should have one line, which contains:
deb http://cloudstack.apt-get.eu/ubuntu precise 4.1
We’ll change it to point to the new package repository:
deb http://cloudstack.apt-get.eu/ubuntu precise 4.3
If you’re using your own package repository, change this line to read as appropriate for your 4.3 repository.
Now update your apt package list:
$ sudo apt-get update
Now that you have the repository configured, it’s time to install the
cloudstack-management
package. This will pull in any other dependencies you need.$ sudo apt-get install cloudstack-management
You will need to manually install the
cloudstack-agent
package:$ sudo apt-get install cloudstack-agent
During the installation of
cloudstack-agent
, APT will copy youragent.properties
,log4j-cloud.xml
, andenvironment.properties
from/etc/cloud/agent
to/etc/cloudstack/agent
.When prompted whether you wish to keep your configuration, say Yes.
Verify that the file
/etc/cloudstack/agent/environment.properties
has a line that reads:paths.script=/usr/share/cloudstack-common
If not, add the line.
Restart the agent:
service cloudstack-agent stop killall jsvc service cloudstack-agent start
(VMware only) Additional steps are required for each VMware cluster. These steps will not affect running guests in the cloud. These steps are required only for clouds using VMware clusters:
Stop the Management Server:
service cloudstack-management stop
Generate the encrypted equivalent of your vCenter password:
java -classpath /usr/share/cloudstack-common/lib/jasypt-1.9.0.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI encrypt.sh input="_your_vCenter_password_" password="`cat /etc/cloudstack/management/key`" verbose=false
Store the output from this step, we need to add this in cluster_details table and vmware_data_center tables in place of the plain text password
Find the ID of the row of cluster_details table that you have to update:
mysql -u <username> -p<password>
select * from cloud.cluster_details;
Update the plain text password with the encrypted one
update cloud.cluster_details set value = '_ciphertext_from_step_1_' where id = _id_from_step_2_;
Confirm that the table is updated:
select * from cloud.cluster_details;
Find the ID of the correct row of vmware_data_center that you want to update
select * from cloud.vmware_data_center;
update the plain text password with the encrypted one:
update cloud.vmware_data_center set password = '_ciphertext_from_step_1_' where id = _id_from_step_5_;
Confirm that the table is updated:
select * from cloud.vmware_data_center;
Start the CloudStack Management server
service cloudstack-management start
(KVM only) Additional steps are required for each KVM host. These steps will not affect running guests in the cloud. These steps are required only for clouds using KVM as hosts and only on the KVM hosts.
Configure the CloudStack yum repository as detailed above.
Stop the running agent.
# service cloud-agent stop
Update the agent software.
# yum update cloudstack-agent
Start the agent.
# service cloudstack-agent start
If you are using CentOS or RHEL, follow this procedure to upgrade your packages. If not, skip to step 13.
注釈
Community Packages: This section assumes you’re using the community supplied packages for CloudStack. If you’ve created your own packages and yum repository, substitute your own URL for the ones used in these examples.
The first order of business will be to change the yum repository for each system with CloudStack packages. This means all management servers, and any hosts that have the KVM agent.
(No changes should be necessary for hosts that are running VMware or Xen.)
Start by opening
/etc/yum.repos.d/cloudstack.repo
on any systems that have CloudStack packages installed.This file should have content similar to the following:
[apache-cloudstack] name=Apache CloudStack baseurl=http://cloudstack.apt-get.eu/rhel/4.1/ enabled=1 gpgcheck=0
If you are using the community provided package repository, change the base url to http://cloudstack.apt-get.eu/rhel/4.3/
If you’re using your own package repository, change this line to read as appropriate for your 4.3 repository.
Now that you have the repository configured, it’s time to install the
cloudstack-management
package by upgrading the oldercloudstack-management
package.$ sudo yum upgrade cloudstack-management
For KVM hosts, you will need to upgrade the
cloud-agent
package, similarly installing the new version ascloudstack-agent
.$ sudo yum upgrade cloudstack-agent
Verify that the file
/etc/cloudstack/agent/environment.properties
has a line that reads:paths.script=/usr/share/cloudstack-common
If not, add the line.
Restart the agent:
service cloudstack-agent stop killall jsvc service cloudstack-agent start
Now it’s time to restart the management server
# service cloudstack-management start
Once you’ve upgraded the packages on your management servers, you’ll need to restart the system VMs. Ensure that the admin port is set to 8096 by using the “integration.api.port” global parameter. This port is used by the cloud-sysvmadm script at the end of the upgrade procedure. For information about how to set this parameter, see “Setting Global Configuration Parameters” in the Installation Guide. Changing this parameter will require management server restart. Also make sure port 8096 is open in your local host firewall to do this.
There is a script that will do this for you, all you need to do is run the script and supply the IP address for your MySQL instance and your MySQL credentials:
# nohup cloudstack-sysvmadm -d IP address -u cloud -p -a > sysvm.log 2>&1 &
You can monitor the log for progress. The process of restarting the system VMs can take an hour or more.
# tail -f sysvm.log
The output to
sysvm.log
will look something like this:Stopping and starting 1 secondary storage vm(s)... Done stopping and starting secondary storage vm(s) Stopping and starting 1 console proxy vm(s)... Done stopping and starting console proxy vm(s). Stopping and starting 4 running routing vm(s)... Done restarting router(s).

Upgrade from 4.0.x to 4.3¶
This section will guide you from CloudStack 4.0.x versions to CloudStack 4.3.
Any steps that are hypervisor-specific will be called out with a note.
警告
Package Structure Changes: The package structure for CloudStack has changed significantly since the 4.0.x releases. If you’ve compiled your own packages, you’ll notice that the package names and the number of packages has changed. This is not a bug. However, this does mean that the procedure is not as simple as an apt-get upgrade
or yum update
, so please follow this section carefully.
We recommend reading through this section once or twice before beginning your upgrade procedure, and working through it on a test system before working on a production system.
Most users of CloudStack manage the installation and upgrades of CloudStack with one of Linux’s predominant package systems, RPM or APT. This guide assumes you’ll be using RPM and Yum (for Red Hat Enterprise Linux or CentOS), or APT and Debian packages (for Ubuntu).
Create RPM or Debian packages (as appropriate) and a repository from the 4.3 source, or check the Apache CloudStack downloads page at http://cloudstack.apache.org/downloads.html for package repositories supplied by community members. You will need them for step 9 or step 10.
Instructions for creating packages from the CloudStack source are in the Installation Guide.
注釈
The following upgrade instructions should be performed regardless of hypervisor type.
While running the existing 4.0.0 system, log in to the UI as root administrator.

Stop your management server or servers. Run this on all management server hosts:
# service cloud-management stop
If you are running a usage server or usage servers, stop those as well:
# service cloud-usage stop
Make a backup of your MySQL database. If you run into any issues or need to roll back the upgrade, this will assist in debugging or restoring your existing environment. You’ll be prompted for your password.
# mysqldump -u root -p cloud > cloudstack-backup.sql
Whether you’re upgrading a Red Hat/CentOS based system or Ubuntu based system, you’re going to need to stop the CloudStack management server before proceeding.
# service cloud-management stop
If you have made changes to
/etc/cloud/management/components.xml
, you’ll need to carry these over manually to the new file,/etc/cloudstack/management/componentContext.xml
. This is not done automatically. (If you’re unsure, we recommend making a backup of the originalcomponents.xml
to be on the safe side.After upgrading to 4.3, API clients are expected to send plain text passwords for login and user creation, instead of MD5 hash. Incase, api client changes are not acceptable, following changes are to be made for backward compatibility:
Modify componentContext.xml, and make PlainTextUserAuthenticator as the default authenticator (1st entry in the userAuthenticators adapter list is default)
<!-- Security adapters --> <bean id="userAuthenticators" class="com.cloud.utils.component.AdapterList"> <property name="Adapters"> <list> <ref bean="PlainTextUserAuthenticator"/> <ref bean="MD5UserAuthenticator"/> <ref bean="LDAPUserAuthenticator"/> </list> </property> </bean>
PlainTextUserAuthenticator works the same way MD5UserAuthenticator worked prior to 4.3.

Watch the screen to be sure that the template downloads successfully and enters the READY state. Do not proceed until this is successful.
(KVM on RHEL 6.0/6.1 only) If your existing CloudStack deployment includes one or more clusters of KVM hosts running RHEL 6.0 or RHEL 6.1, perform the following:
Ensure that you upgrade the operating system version on those hosts before upgrading CloudStack
To do that, change the yum repository for each system with CloudStack packages, that implies that all the Management Servers and any hosts that have the KVM agent.
Open
/etc/yum.repos.d/cloudstack.repo
on any systems that have CloudStack packages installed.Edit as follows:
[upgrade] name=rhel63 baseurl=url-of-your-rhel6.3-repo enabled=1 gpgcheck=0 [apache CloudStack] name= Apache CloudStack baseurl= http://cloudstack.apt-get.eu/rhel/4.3/ enabled=1 gpgcheck=0
If you are using the community provided package repository, change the baseurl to http:// cloudstack.apt-get.eu/rhel/4.3/
If you are using your own package repository, change this line to read as appropriate for your 4.3 repository.
Now that you have the repository configured, upgrade the host operating system from RHEL 6.0 to 6.3:
# yum upgrade
Stop all Usage Servers if running. Run this on all Usage Server hosts.
# service cloud-usage stop
Stop the Management Servers. Run this on all Management Server hosts.
# service cloud-management stop
On the MySQL master, take a backup of the MySQL databases. We recommend performing this step even in test upgrades. If there is an issue, this will assist with debugging.
In the following commands, it is assumed that you have set the root password on the database, which is a CloudStack recommended best practice. Substitute your own MySQL root password.
# mysqldump -u root -pmysql_password cloud > cloud-backup.dmp # mysqldump -u root -pmysql_password cloud_usage > cloud-usage-backup.dmp
Either build RPM/DEB packages as detailed in the Installation Guide, or use one of the community provided yum/apt repositories to gain access to the CloudStack binaries.
If you are using Ubuntu, follow this procedure to upgrade your packages. If not, skip to step 8.

If you have made changes to your copy of
/etc/cloud/management/components.xml
the changes will be preserved in the upgrade. However, you need to do the following steps to place these changes in a new version of the file which is compatible with version 4.2.x.Make a backup copy of
/etc/cloud/management/components.xml
. For example:# mv /etc/cloud/management/components.xml /etc/cloud/management/components.xml-backup
Copy
/etc/cloud/management/components.xml.rpmnew
to create a new/etc/cloud/management/components.xml
:# cp -ap /etc/cloud/management/components.xml.rpmnew /etc/cloud/management/components.xml
Merge your changes from the backup file into the new
components.xml
.# vi /etc/cloudstack/management/components.xml
注釈
If you have more than one management server node, repeat the upgrade steps on each node.
After upgrading to 4.3, API clients are expected to send plain text passwords for login and user creation, instead of MD5 hash. Incase, api client changes are not acceptable, following changes are to be made for backward compatibility:

PlainTextUserAuthenticator works the same way MD5UserAuthenticator worked prior to 4.3
Start the first Management Server. Do not start any other Management Server nodes yet.
# service cloudstack-management start
Wait until the databases are upgraded. Ensure that the database upgrade is complete. After confirmation, start the other Management Servers one at a time by running the same command on each node.
注釈
Failing to restart the Management Server indicates a problem in the upgrade. Having the Management Server restarted without any issues indicates that the upgrade is successfully completed.
Start all Usage Servers (if they were running on your previous version). Perform this on each Usage Server host.
# service cloudstack-usage start
Additional steps are required for each KVM host. These steps will not affect running guests in the cloud. These steps are required only for clouds using KVM as hosts and only on the KVM hosts.
Configure a yum or apt repository containing the CloudStack packages as outlined in the Installation Guide.
Stop the running agent.
# service cloud-agent stop
Update the agent software with one of the following command sets as appropriate for your environment.
# yum update cloud-*
# apt-get update
# apt-get upgrade cloud-*
Edit
/etc/cloudstack/agent/agent.properties
to change the resource parameter from “com.cloud.agent.resource.computing.LibvirtComputingResource” to “com.cloud.hypervisor.kvm.resource.LibvirtComputingResource”.Upgrade all the existing bridge names to new bridge names by running this script:
# cloudstack-agent-upgrade
Install a libvirt hook with the following commands:
# mkdir /etc/libvirt/hooks # cp /usr/share/cloudstack-agent/lib/libvirtqemuhook /etc/libvirt/hooks/qemu # chmod +x /etc/libvirt/hooks/qemu
Restart libvirtd.
# service libvirtd restart
Start the agent.
# service cloudstack-agent start
When the Management Server is up and running, log in to the CloudStack UI and restart the virtual router for proper functioning of all the features.
Log in to the CloudStack UI as administrator, and check the status of the hosts. All hosts should come to Up state (except those that you know to be offline). You may need to wait 20 or 30 minutes, depending on the number of hosts.
注釈
Troubleshooting: If login fails, clear your browser cache and reload the page.
Do not proceed to the next step until the hosts show in Up state.
If you are upgrading from 3.0.x, perform the following:
Ensure that the admin port is set to 8096 by using the “integration.api.port” global parameter.
This port is used by the cloud-sysvmadm script at the end of the upgrade procedure. For information about how to set this parameter, see “Setting Global Configuration Parameters” in the Installation Guide.
Restart the Management Server.
注釈
If you don’t want the admin port to remain open, you can set it to null after the upgrade is done and restart the management server.
Run the
cloudstack-sysvmadm
script to stop, then start, all Secondary Storage VMs, Console Proxy VMs, and virtual routers. Run the script once on each management server. Substitute your own IP address of the MySQL instance, the MySQL user to connect as, and the password to use for that user. In addition to those parameters, provide the-c
and-r
arguments. For example:# nohup cloudstack-sysvmadm -d 192.168.1.5 -u cloud -p password -c -r > sysvm.log 2>&1 &
# tail -f sysvm.log
This might take up to an hour or more to run, depending on the number of accounts in the system.
If needed, upgrade all Citrix XenServer hypervisor hosts in your cloud to a version supported by CloudStack 4.3. The supported versions are XenServer 5.6 SP2 and 6.0.2. Instructions for upgrade can be found in the CloudStack 4.3 Installation Guide under “Upgrading XenServer Versions.”
Now apply the XenServer hotfix XS602E003 (and any other needed hotfixes) to XenServer v6.0.2 hypervisor hosts.
Disconnect the XenServer cluster from CloudStack.
In the left navigation bar of the CloudStack UI, select Infrastructure. Under Clusters, click View All. Select the XenServer cluster and click Actions - Unmanage.
This may fail if there are hosts not in one of the states Up, Down, Disconnected, or Alert. You may need to fix that before unmanaging this cluster.
Wait until the status of the cluster has reached Unmanaged. Use the CloudStack UI to check on the status. When the cluster is in the unmanaged state, there is no connection to the hosts in the cluster.
To clean up the VLAN, log in to one XenServer host and run:
/opt/xensource/bin/cloud-clean-vlan.sh
Now prepare the upgrade by running the following on one XenServer host:
/opt/xensource/bin/cloud-prepare-upgrade.sh
If you see a message like “can’t eject CD”, log in to the VM and unmount the CD, then run this script again.
Upload the hotfix to the XenServer hosts. Always start with the Xen pool master, then the slaves. Using your favorite file copy utility (e.g. WinSCP), copy the hotfixes to the host. Place them in a temporary folder such as /tmp.
On the Xen pool master, upload the hotfix with this command:
xe patch-upload file-name=XS602E003.xsupdate
Make a note of the output from this command, which is a UUID for the hotfix file. You’ll need it in another step later.
注釈
(Optional) If you are applying other hotfixes as well, you can repeat the commands in this section with the appropriate hotfix number. For example, XS602E004.xsupdate.
Manually live migrate all VMs on this host to another host. First, get a list of the VMs on this host:
# xe vm-list
Then use this command to migrate each VM. Replace the example host name and VM name with your own:
# xe vm-migrate live=true host=host-name
vm=``VM-name``注釈
Troubleshooting: If you see a message like “You attempted an operation on a VM which requires PV drivers to be installed but the drivers were not detected,” run:
/opt/xensource/bin/make_migratable.sh b6cf79c8-02ee-050b-922f-49583d9f1a14
.Apply the hotfix. First, get the UUID of this host:
# xe host-list
Then use the following command to apply the hotfix. Replace the example host UUID with the current host ID, and replace the hotfix UUID with the output from the patch-upload command you ran on this machine earlier. You can also get the hotfix UUID by running xe patch-list.
xe patch-apply host-uuid=host-uuid uuid=hotfix-uuid
Copy the following files from the CloudStack Management Server to the host.
Copy from here... ...to here /usr/lib64/cloud/common /scripts/vm/hypervisor/ xenserver/xenserver60/N FSSR.py /opt/xensource/sm/NFSSR.py /usr/lib64/cloud/common /scripts/vm/hypervisor/ xenserver/setupxenserve r.sh /opt/xensource/bin/setupxenserver.sh /usr/lib64/cloud/common /scripts/vm/hypervisor/ xenserver/make_migrata ble.sh /opt/xensource/bin/make_migratable.sh (Only for hotfixes XS602E005 and XS602E007) You need to apply a new Cloud Support Pack.
Download the CSP software onto the XenServer host from one of the following links:

Troubleshooting Tip: If passwords which you know to be valid appear not to work after upgrade, or other UI issues are seen, try clearing your browser cache and reloading the UI page.
Upgrade from 2.2.14 to 4.3¶
Ensure that you query your IPaddress usage records and process them; for example, issue invoices for any usage that you have not yet billed users for.
Starting in 3.0.2, the usage record format for IP addresses is the same as the rest of the usage types. Instead of a single record with the assignment and release dates, separate records are generated per aggregation period with start and end dates. After upgrading to 4.3, any existing IP address usage records in the old format will no longer be available.
If you are using version 2.2.0 - 2.2.13, first upgrade to 2.2.14 by using the instructions in the 2.2.14 Release Notes.
警告
KVM Hosts: If KVM hypervisor is used in your cloud, be sure you completed the step to insert a valid username and password into the host_details table on each KVM node as described in the 2.2.14 Release Notes. This step is critical, as the database will be encrypted after the upgrade to 4.3.
While running the 2.2.14 system, log in to the UI as root administrator.
Using the UI, add a new System VM template for each hypervisor type that is used in your cloud. In each zone, add a system VM template for each hypervisor used in that zone
In the left navigation bar, click Templates.
In Select view, click Templates.
Click Register template.
The Register template dialog box is displayed.
In the Register template dialog box, specify the following values depending on the hypervisor type (do not change these):

Watch the screen to be sure that the template downloads successfully and enters the READY state. Do not proceed until this is successful
WARNING: If you use more than one type of hypervisor in your cloud, be sure you have repeated these steps to download the system VM template for each hypervisor type. Otherwise, the upgrade will fail.
(KVM on RHEL 6.0/6.1 only) If your existing CloudStack deployment includes one or more clusters of KVM hosts running RHEL 6.0 or RHEL 6.1, perform the following:
Ensure that you upgrade the operating system version on those hosts before upgrading CloudStack
To do that, change the yum repository for each system with CloudStack packages, that implies that all the Management Servers and any hosts that have the KVM agent.
Open
/etc/yum.repos.d/cloudstack.repo
on any systems that have CloudStack packages installed.Edit as follows:
[upgrade] name=rhel63 baseurl=url-of-your-rhel6.3-repo enabled=1 gpgcheck=0 [apache CloudStack] name= Apache CloudStack baseurl= http://cloudstack.apt-get.eu/rhel/4.2/ enabled=1 gpgcheck=0
If you are using the community provided package repository, change the baseurl to http:// cloudstack.apt-get.eu/rhel/4.2/
If you are using your own package repository, change this line to read as appropriate for your 4.2 repository.
Now that you have the repository configured, upgrade the host operating system from RHEL 6.0 to 6.3:
# yum upgrade
Stop all Usage Servers if running. Run this on all Usage Server hosts.
# service cloud-usage stop
Stop the Management Servers. Run this on all Management Server hosts.
# service cloud-management stop
On the MySQL master, take a backup of the MySQL databases. We recommend performing this step even in test upgrades. If there is an issue, this will assist with debugging.
In the following commands, it is assumed that you have set the root password on the database, which is a CloudStack recommended best practice. Substitute your own MySQL root password.
# mysqldump -u root -pmysql_password cloud > cloud-backup.dmp # mysqldump -u root -pmysql_password cloud_usage > cloud-usage-backup.dmp
Either build RPM/DEB packages as detailed in the Installation Guide, or use one of the community provided yum/apt repositories to gain access to the CloudStack binaries.
If you are using Ubuntu, follow this procedure to upgrade your packages. If not, skip to step 13.
注釈
Community Packages: This section assumes you’re using the community supplied packages for CloudStack. If you’ve created your own packages and APT repository, substitute your own URL for the ones used in these examples.
The first order of business will be to change the sources list for each system with CloudStack packages. This means all management servers, and any hosts that have the KVM agent. (No changes should be necessary for hosts that are running VMware or Xen.)
Start by opening
/etc/apt/sources.list.d/cloudstack.list
on any systems that have CloudStack packages installed.This file should have one line, which contains:
deb http://cloudstack.apt-get.eu/ubuntu precise 4.0
We’ll change it to point to the new package repository:
deb http://cloudstack.apt-get.eu/ubuntu precise 4.3
If you’re using your own package repository, change this line to read as appropriate for your 4.2 repository.
Now update your apt package list:
$ sudo apt-get update
Now that you have the repository configured, it’s time to install the
cloudstack-management
package. This will pull in any other dependencies you need.$ sudo apt-get install cloudstack-management
On KVM hosts, you will need to manually install the
cloudstack-agent
package:$ sudo apt-get install cloudstack-agent
During the installation of
cloudstack-agent
, APT will copy youragent.properties
,log4j-cloud.xml
, andenvironment.properties
from/etc/cloud/agent
to/etc/cloudstack/agent
.When prompted whether you wish to keep your configuration, say Yes.
Verify that the file
/etc/cloudstack/agent/environment.properties
has a line that reads:paths.script=/usr/share/cloudstack-common
If not, add the line.
Restart the agent:
service cloud-agent stop killall jsvc service cloudstack-agent start
During the upgrade,
log4j-cloud.xml
was simply copied over, so the logs will continue to be added to/var/log/cloud/agent/agent.log
. There’s nothing wrong with this, but if you prefer to be consistent, you can change this by copying over the sample configuration file:cd /etc/cloudstack/agent mv log4j-cloud.xml.dpkg-dist log4j-cloud.xml service cloudstack-agent restart
Once the agent is running, you can uninstall the old cloud-* packages from your system:
sudo dpkg --purge cloud-agent
If you are using CentOS or RHEL, follow this procedure to upgrade your packages. If not, skip to step 14.
注釈
Community Packages: This section assumes you’re using the community supplied packages for CloudStack. If you’ve created your own packages and yum repository, substitute your own URL for the ones used in these examples.
The first order of business will be to change the yum repository for each system with CloudStack packages. This means all management servers, and any hosts that have the KVM agent. (No changes should be necessary for hosts that are running VMware or Xen.)
Start by opening
/etc/yum.repos.d/cloudstack.repo
on any systems that have CloudStack packages installed.This file should have content similar to the following:
[apache-cloudstack] name=Apache CloudStack baseurl=http://cloudstack.apt-get.eu/rhel/4.0/ enabled=1 gpgcheck=0
If you are using the community provided package repository, change the baseurl to http://cloudstack.apt-get.eu/rhel/4.2/
If you’re using your own package repository, change this line to read as appropriate for your 4.3 repository.
Now that you have the repository configured, it’s time to install the
cloudstack-management
package by upgrading the oldercloud-client
package.$ sudo yum upgrade cloud-client
For KVM hosts, you will need to upgrade the
cloud-agent
package, similarly installing the new version ascloudstack-agent
.$ sudo yum upgrade cloud-agent
During the installation of
cloudstack-agent
, the RPM will copy youragent.properties
,log4j-cloud.xml
, andenvironment.properties
from/etc/cloud/agent
to/etc/cloudstack/agent
.Verify that the file
/etc/cloudstack/agent/environment.properties
has a line that reads:paths.script=/usr/share/cloudstack-common
If not, add the line.
Restart the agent:
service cloud-agent stop killall jsvc service cloudstack-agent start
If you have made changes to your existing copy of the file components.xml in your previous-version CloudStack installation, the changes will be preserved in the upgrade. However, you need to do the following steps to place these changes in a new version of the file which is compatible with version 4.0.0-incubating.
注釈
How will you know whether you need to do this? If the upgrade output in the previous step included a message like the following, then some custom content was found in your old components.xml, and you need to merge the two files:
warning: /etc/cloud/management/components.xml created as /etc/cloud/management/components.xml.rpmnew
Make a backup copy of your
/etc/cloud/management/components.xml
file. For example:# mv /etc/cloud/management/components.xml /etc/cloud/management/components.xml-backup
Copy
/etc/cloud/management/components.xml.rpmnew
to create a new/etc/cloud/management/components.xml
:# cp -ap /etc/cloud/management/components.xml.rpmnew /etc/cloud/management/components.xml
Merge your changes from the backup file into the new components.xml file.
# vi /etc/cloudstack/management/components.xml
After upgrading to 4.3, API clients are expected to send plain text passwords for login and user creation, instead of MD5 hash. If API client changes are not acceptable, following changes are to be made for backward compatibility:
Modify componentContext.xml, and make PlainTextUserAuthenticator as the default authenticator (1st entry in the userAuthenticators adapter list is default)
<!-- Security adapters --> <bean id="userAuthenticators" class="com.cloud.utils.component.AdapterList"> <property name="Adapters"> <list> <ref bean="PlainTextUserAuthenticator"/> <ref bean="MD5UserAuthenticator"/> <ref bean="LDAPUserAuthenticator"/> </list> </property> </bean>
PlainTextUserAuthenticator works the same way MD5UserAuthenticator worked prior to 4.2.
If you have made changes to your existing copy of the
/etc/cloud/management/db.properties
file in your previous-version CloudStack installation, the changes will be preserved in the upgrade. However, you need to do the following steps to place these changes in a new version of the file which is compatible with this version.Make a backup copy of your file
/etc/cloud/management/db.properties
. For example:# mv /etc/cloud/management/db.properties /etc/cloud/management/db.properties-backup
Copy
/etc/cloud/management/db.properties.rpmnew
to create a new/etc/cloud/management/db.properties
:# cp -ap /etc/cloud/management/db.properties.rpmnew etc/cloud/management/db.properties
Merge your changes from the backup file into the new db.properties file.
# vi /etc/cloudstack/management/db.properties
On the management server node, run the following command. It is recommended that you use the command-line flags to provide your own encryption keys. See Password and Key Encryption in the Installation Guide.
# cloudstack-setup-encryption -e encryption_type -m management_server_key -k database_key
When used without arguments, as in the following example, the default encryption type and keys will be used:
- (Optional) For encryption_type, use file or web to indicate the technique used to pass in the database encryption password. Default: file.
- (Optional) For management_server_key, substitute the default key that is used to encrypt confidential parameters in the properties file. Default: password. It is highly recommended that you replace this with a more secure value
- (Optional) For database_key, substitute the default key that is used to encrypt confidential parameters in the CloudStack database. Default: password. It is highly recommended that you replace this with a more secure value.
Repeat steps 10 - 14 on every management server node. If you provided your own encryption key in step 14, use the same key on all other management servers.
Start the first Management Server. Do not start any other Management Server nodes yet.
# service cloudstack-management start
Wait until the databases are upgraded. Ensure that the database upgrade is complete. You should see a message like “Complete! Done.” After confirmation, start the other Management Servers one at a time by running the same command on each node.
Start all Usage Servers (if they were running on your previous version). Perform this on each Usage Server host.
# service cloudstack-usage start
(KVM only) Perform the following additional steps on each KVM host.
These steps will not affect running guests in the cloud. These steps are required only for clouds using KVM as hosts and only on the KVM hosts.
Configure your CloudStack package repositories as outlined in the Installation Guide
Stop the running agent.
# service cloud-agent stop
Update the agent software with one of the following command sets as appropriate.
# yum update cloud-*
# apt-get update # apt-get upgrade cloud-*
Copy the contents of the
agent.properties
file to the newagent.properties
file by using the following commandsed -i 's/com.cloud.agent.resource.computing.LibvirtComputingResource/com.cloud.hypervisor.kvm.resource.LibvirtComputingResource/g' /etc/cloudstack/agent/agent.properties
Upgrade all the existing bridge names to new bridge names by running this script:
# cloudstack-agent-upgrade
Install a libvirt hook with the following commands:
# mkdir /etc/libvirt/hooks # cp /usr/share/cloudstack-agent/lib/libvirtqemuhook /etc/libvirt/hooks/qemu # chmod +x /etc/libvirt/hooks/qemu
Restart libvirtd.
# service libvirtd restart
Start the agent.
# service cloudstack-agent start
When the Management Server is up and running, log in to the CloudStack UI and restart the virtual router for proper functioning of all the features.
Log in to the CloudStack UI as admin, and check the status of the hosts. All hosts should come to Up state (except those that you know to be offline). You may need to wait 20 or 30 minutes, depending on the number of hosts.
Do not proceed to the next step until the hosts show in the Up state. If the hosts do not come to the Up state, contact support.
Run the following script to stop, then start, all Secondary Storage VMs, Console Proxy VMs, and virtual routers.
Run the command once on one management server. Substitute your own IP address of the MySQL instance, the MySQL user to connect as, and the password to use for that user. In addition to those parameters, provide the “-c” and “-r” arguments. For example:
# nohup cloudstack-sysvmadm -d 192.168.1.5 -u cloud -p password -c -r > sysvm.log 2>&1 & # tail -f sysvm.log
This might take up to an hour or more to run, depending on the number of accounts in the system.
After the script terminates, check the log to verify correct execution:
# tail -f sysvm.log
The content should be like the following:
Stopping and starting 1 secondary storage vm(s)... Done stopping and starting secondary storage vm(s) Stopping and starting 1 console proxy vm(s)... Done stopping and starting console proxy vm(s). Stopping and starting 4 running routing vm(s)... Done restarting router(s).
If you would like additional confirmation that the new system VM templates were correctly applied when these system VMs were rebooted, SSH into the System VM and check the version.
Use one of the following techniques, depending on the hypervisor.
XenServer or KVM:
SSH in by using the link local IP address of the system VM. For example, in the command below, substitute your own path to the private key used to log in to the system VM and your own link local IP.
Run the following commands on the XenServer or KVM host on which the system VM is present:
# ssh -i private-key-path link-local-ip -p 3922 # cat /etc/cloudstack-release
The output should be like the following:
Cloudstack Release 4.0.0-incubating Mon Oct 9 15:10:04 PST 2012
ESXi:
SSH in using the private IP address of the system VM. For example, in the command below, substitute your own path to the private key used to log in to the system VM and your own private IP.
Run the following commands on the Management Server:
# ssh -i private-key-path private-ip -p 3922 # cat /etc/cloudstack-release
The output should be like the following:
Cloudstack Release 4.0.0-incubating Mon Oct 9 15:10:04 PST 2012
If needed, upgrade all Citrix XenServer hypervisor hosts in your cloud to a version supported by CloudStack 4.0.0-incubating. The supported versions are XenServer 5.6 SP2 and 6.0.2. Instructions for upgrade can be found in the CloudStack 4.0.0-incubating Installation Guide.
Apply the XenServer hotfix XS602E003 (and any other needed hotfixes) to XenServer v6.0.2 hypervisor hosts.
Disconnect the XenServer cluster from CloudStack.
In the left navigation bar of the CloudStack UI, select Infrastructure. Under Clusters, click View All. Select the XenServer cluster and click Actions - Unmanage.
This may fail if there are hosts not in one of the states Up, Down, Disconnected, or Alert. You may need to fix that before unmanaging this cluster.
Wait until the status of the cluster has reached Unmanaged. Use the CloudStack UI to check on the status. When the cluster is in the unmanaged state, there is no connection to the hosts in the cluster.
To clean up the VLAN, log in to one XenServer host and run:

Prepare the upgrade by running the following on one XenServer host:
/opt/xensource/bin/cloud-prepare-upgrade.sh
If you see a message like “can’t eject CD”, log in to the VM and umount the CD, then run this script again.
Upload the hotfix to the XenServer hosts. Always start with the Xen pool master, then the slaves. Using your favorite file copy utility (e.g. WinSCP), copy the hotfixes to the host. Place them in a temporary folder such as /root or /tmp.
On the Xen pool master, upload the hotfix with this command:
xe patch-upload file-name=XS602E003.xsupdate
Make a note of the output from this command, which is a UUID for the hotfix file. You’ll need it in another step later.
注釈
(Optional) If you are applying other hotfixes as well, you can repeat the commands in this section with the appropriate hotfix number. For example, XS602E004.xsupdate.
Manually live migrate all VMs on this host to another host. First, get a list of the VMs on this host:
