This version of CloudStack allows control over the visibility of the DNS services provided by the Virtual Router in Shared networks. By default CloudStack allows DNS queries via the Guest interface from any IP address. This allows for the DNS resolution of guest VMs on the Shared network by services outside of the shared network. While this can be useful, it can also be an issue on Shared Networks which are using Internet routable/public (i.e. non-RFC1918) IP addresses, as the DNS service is then queriable from the public internet at large. A new global setting “expose.dns.externally” has been added (with a default value of “true” in order to keep backward compatibility) which controls whether the source of DNS queries should be limited to only hosts on the Shared Network guest subnet or not. If you wish to disable ‘outside’ access to the DNS services running on Virtual Routers; set the value to “false” and recreate the related Virtual Routers.
Apache CloudStack powers numerous elastic Cloud computing services, including solutions that have ranked as Gartner Magic Quadrant leaders. Highlighted in the Forrester Q4 2017 Enterprise Open Source Cloud Adoption report, Apache CloudStack “sits beneath hundreds of service provider clouds”, including Fortune 5 multinational corporations.

Libvirt Python Dependency on KVM and CentOS¶
For CentOS users using the security groups feature on KVM it is needed to install the epel-release and python36-libvirt packages.
Workaround for adding newer KVM hosts¶
Newer GNU/Linux distributions with latest OpenSSH package disables some older SSH algorithms and ciphers and newer algorithms are not supported by trilead-ssh library used by CloudStack to SSH into KVM hosts during the host-add operation. Until the dependency library can support that users can use the following workaround in their KVM host’s /etc/ssh/sshd_config and restart ssh server before adding the KVM host in CloudStack:
New UI GA and Legacy UI Deprecation and Removal Notice¶
Cloudstack 4.15 ships with the GA release of a new and modern User Interface as the default UI which deprecates the current legacy UI. With version 4.15, the existing legacy UI (deprecated) along with the new UI are the supported UI for production environments.
The default URL <host>:8080/client will serve the new UI and <host>:8080/client/legacy will serve the deprecated legacy UI.
In the next release (4.16), the Apache Cloudstack community will remove the legacy UI. Users are encouraged to implement a migration path towards deprecating the legacy UI in their production environments.
