Java Version Requirement

CloudStack 4.22 requires installation of Java 17 JRE for management server and the KVM agent. On installing or upgrading cloudstack-management and/or cloudstack-agent packages, please configure Java 17 as the default java version using:

$ sudo alternatives --config java

Note: For Ubuntu distributions where the openjdk-17 packages are not available from the main repositories, the JRE can be installed from an external PPA such as openjdk-r. The PPA can be added before installation/upgrade:

$ sudo add-apt-repository ppa:openjdk-r/ppa
$ sudo apt-get update
