I'm pleased to announce the release of OpenVZ 8.0 Alpha Release. The new
release focuses on rebasing OpenVZ to the latest Red Hat Enterprise
Linux 8.4 with 4.18.0-x kernel.
This version is not ready for production use. While we don't intend to
release broken builds, these releases are very early in development, and
not supported for production use, as they may contain errors, and any
resulting instability could cause crashes or data loss, so you should
not deploy this to a production environment. Instead, please try out the
builds in a lab or test environment.
* Simplified installation program.
* 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.
* 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,
SUSE Linux Enterprise Server 12 and 15. Additionally, these guest
operating systems are supported in virtual machines only: Windows
Server 2016, Windows Server 2019, Windows Server 2022. Migrated
containers and virtual machines with older guest operating systems
should continue to work.
* OpenVZ 8.0 Alpha is based on Red Hat Enterprise Linux 8.4 as well as
the 4.18.0-x kernels.
* Libvirt storage pools and volumes can be used.
* Problem reports can be collected and sent using the 'vzreport' tool.
* The 'ip_conntrack_disable_ve0' option of the nf_conntrack kernel
module has been dropped. Connection tracking is now enabled
automatically if required by iptables rules. Otherwise, it remains
* Resizing container disks may fail
* Microsoft Windows virtual machines created on this alpha build may not
* Virtual machine snapshots may not work
* Network interface hotplugging may not work
