OpenVZ 7.0 GA

OpenVZ 7.0 has been released. The new release focuses on merging OpenVZ and Virtuozzo source codebase, replacing our own hypervisor with KVM.

Key changes in comparison to the last stable OpenVZ release:

• OpenVZ 7.0 becomes a complete Linux distribution based on our own VzLinux.
• The main difference between the Virtuozzo (commercial) and OpenVZ (free) versions are the EULA, packages with paid features, and Anaconda installer.
• The user documentation is publicly available.
• EZ templates can be used instead of tarballs with template caches.
• Additional features (see announce)

Virtuozzo 7 Beta

This Virtuozzo 7.0 Beta offers the following major improvements:

Unified management of containers and KVM virtual machines with the prlctl tool and SDK. You get a single universal toolset for all CT/VM management needs.

Autoballooning and kernel same-page merging that allows overcommitting memory resources in the smartest way possible with an insignificant impact on customer workloads.

Memory hotplugging for containers and VMs that allows both increasing and reducing CT/VM memory size on the fly, without the need to reboot. Your customers can now scale their workloads without any downtime. This feature also enables you to make PAYG offerings, allowing customers to change VM resources depending on workload and potentially pay less.

Memory guarantees for both containers and virtual machines.

Ability to manage containers and VMs with libvirt and virt-manager. If you used to manage VMs with libvirt, you can do it in Virtuozzo in absolutely the same way.

Guest tools for Windows and Linux VMs.
