Supported Guest Operating Systems Reference

Virtuozzo is committed to providing high-quality, cost-effective solutions to our customers. Rapidly changing technologies influence the level, timing, and character of demand for particular product versions and components. All of these drive the need to introduce new products and services and to stop testing and supporting specific guest operating systems.

This reference intends to provide the list of guest OSs supported by a particular version of Virtuozzo Server.

Find below information on guest OSs tested and supported in virtual machines and containers and the list of legacy (end-of-life) guest OSs.

Guest OSs Supported in Virtual Machines

Guest OSs Supported in Containers

Notes and Known Limitations

• FreeBSD 10.x and FreeBSD 9.x cannot work inside the virtual machines with UEFI boot enabled.
• FreeBSD 8.x is not supported due to SCSI limitations. Instead, you can try to configure the OS manually and use IDE controllers.
• Hotplug features for FreeBSD and some functions of FreeBSD guest tools are not fully implemented yet.
• To avoid situations when cloned virtual machines obtain duplicate IP addresses via DHCP, regenerate machine-id for the cloned Ubuntu virtual machines or set the Netplan dhcp-identifier parameter to mac.
• The following limitations apply to SUSE Linux Enterprise Server 15 SP6 virtual machines:

  • Ensure the cloud-init package is installed before changing a password in stopped SUSE Linux Enterprise Server 15 SP6 virtual machines.

  • The first automatic installation of Virtuozzo guest tools to a running SUSE Linux Enterprise Server/Desktop 15 SP6 virtual machine with the vz-guest-tools-updater tool requires stopping the VM. If you prefer the first-time installation of the guest tools without downtime, install them manually from our system ISO after ensuring the previously mounted ISO is ejected. Use the following CLI command:

    1	# prlctl installtools MyVM

    Otherwise, via Virtuozzo Automator, go to the Configure tab and select Install Guest Tools.

    With the Virtuozzo guest tools set up, the subsequent run of vz-guest-tools-updater for the running VM will update the guest tools online (without downtime) to the latest version.

  • A cloned SUSE Linux Enterprise Server 15 SP6 virtual machine gets a NIC name with an index increased by one. For example, if an original NIC name is eth0, it will acquire +1 to its existing name. Thus, the name will change to eth1. The subsequent clone operation from the cloned VM will cause the same changes to the NIC name of a newly cloned VM, i.e., eth2, eth3, etc.

  • To avoid situations when cloned SUSE Linux Enterprise Server 15 SP6 virtual machines obtain duplicate IP addresses via DHCP, regenerate machine-id according to the instructions from Resolving Duplicate Machine IDs in Cloned Salt Clients.

  • Since we do not fix the /etc/hosts file for an FQDN resolved without DNS servers, we recommend adding records on your own, if needed, using a local host address or valid current IP address, as follows:

    1	# echo '127.0.0.2 sles15sp6srv01.mqa.dev' >> /etc/hosts

    or

    1	# echo '192.168.1.1 sles15sp6srv01.mqa.dev' >> /etc/hosts

    Otherwise, you can follow the SUSE Linux Enterprise Administration Guide.

Experimental Support of Guest OSs in Virtual Machines

• AlmaLinux 9.x

Experimental Support of Guest OSs in Containers

• CentOS Stream 9

Legacy (End-of-life) Guest OSs

We highly recommend upgrading or using new versions of supported operating systems. Using an end-of-life operating system may cause technical issues in the future, as we no longer test such an operating system.
