Issue date: 2022-02-03
Applies to: Virtuozzo Hybrid Server 9
Virtuozzo Advisory ID: VZA-2022-005
The purpose of Virtuozzo Hybrid Server 9 alpha is to demonstrate the work in progress. The alpha version offers a few new features and supports creating virtual machines and containers with a limited number of guest operating systems.
2. New Features¶
The alpha version is based on Red Hat Enterprise Linux 9 Beta as well as 5.14.x Linux kernels, QEMU 6.0.x, libvirt 7.6.x.
Supported guest operating systems for creating new containers and virtual machines are: VzLinux 7 and 8, Red Hat Enterprise Linux 7 and 8, CentOS 7, AlmaLinux 8, Debian 10, Ubuntu 18.04 LTS and 20.04 LTS. Additionally, these guest operating systems are supported in virtual machines only: Microsoft Windows Server 2016, 2019, and 2022. Migrated containers and virtual machines with older guest operating systems should continue to work.
XFS is now the default file system for containers.
QCOW2 disk images can be used as container virtual disks.
The dispatcher component is now optional and not installed by default as are the ‘prl*’ tools like ‘prlctl’. The primary API for managing virtual environments is now libvirt. The tools for managing virtual environments are now ‘virsh’ and ‘virt-install’. The Parallels SDK as well as the ‘prl*’ tools can be installed for backward compatibility.
3. Known Issues¶
Virtual machine snapshots may not work.
Backups are not implemented yet.
