Virtuozzo Hybrid Server Supported Guest Operating Systems Guide¶

Guest Operating Systems Supported in Virtual Machines¶

Guest Operating Systems 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:

    # 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:

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

    or

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

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

Experimental Support of Guest Operating Systems in Virtual Machines¶

• AlmaLinux 9.x

Legacy (End-of-life) Guest Operating Systems¶

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.
