Hello, We are pleased to announce the official release of Virtuozzo 7.0 Beta.
Some years ago we introduced our own hypervisor technology in Parallels Cloud Server in addition to our containers. Such an offering added more flexibility to Virtuozzo, as in some cases customers preferred traditional hypervisor solutions over containers. Fast and reliable, Virtuozzo hypervisor offered a lot of enterprise features answering the needs of service providers. Nowadays KVM has become fast and reliable enough to suite our customers' needs. For this reason, we do not need to develop and support our own hypervisor anymore. Yet KVM still lacks many required features and we are eager to implement such functionality in our new Virtuozzo 7 with KVM-based virtualization. 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. Also we have prepared homework in case you will want to walk through the new Virtuozzo 7 features [0]. Known Issues ============ The list of known issues and limitations is provided in the README [1]. Download ======== All binary components as well as installation ISO images are available for everyone [2]. The source code of each component is available in the public repository [3]. FAQ === Q: Can we use the binaries or Virtuozzo 7.0 Beta distribution in production? A: No. Virtuozzo 7 is in the beta stage and may contain serious bugs, so we strongly recommend against any use in production. New features are in development. We won't support upgrade from Virtuozzo 7.0 Beta to RTM. Q: Is it possible to upgrade OpenVZ stable to Virtuozzo 7? A: Yes! You can migrate containers from OpenVZ to Virtuozzo using the script [4]. Feedback ======== Our switching to the open development process is an attempt to work more closely with the OpenVZ community. You can help us by sending your feedback to the users@ mail list [5] or submitting a bug in case of serious issues [6].
