OpenVZ 8.0 alpha release

MannDudeMannDude Host Rep, Veteran

Per https://lists.openvz.org/pipermail/users/2021-September/008160.html

Hi,

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.

New Features

  • 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
    disabled.

Known Issues

  • Resizing container disks may fail

  • Microsoft Windows virtual machines created on this alpha build may not
    work

  • Virtual machine snapshots may not work

  • Network interface hotplugging may not work

  • While we don't intend to release broken builds

    That would be something.

    I wonder what the market share for OpenVZ is nowadays? Seems like the demand for it has drastically decreased, it's becoming increasingly rare to see it used.

    Did I read correctly that this is not meant for production use ?

    That's what it says: "This version is not ready for production use."

    Alpha is in a early stage, likely high unstable.

  • The market of containerization is much smaller compared to what it use to be, due to cheaper RAM. And few other containerization stacks that could work on latest kernel also eliminates lots market share of OpenVZ. LXC is almost a dropin replacement, at least for pve proxmox. I am not sure if anyone still choose OpenVZ for new hosting services, does OpenVZ has anything technically superior than LXC and other alternatives?
