Publishing of Virtuozzo builds



We are ready to announce publishing of binaries compiled from open components:


  • Virtuozzo installation ISO image

  • RPM packages (kernel and userspace)

  • Source RPM packages (kernel and userspace)

  • Debug RPM packages (kernel and userspace)

  • EZ templates (CentOS 7 x86_64, CentOS 6 x86_64 etc)

All installation paths described in OpenVZ wiki.

FAQ (Frequently Asked Questions)

Q: Can we use binaries or Virtuozzo distribution in production?
A: No. Virtuozzo 7 is in pre-Beta stage and we strongly recommend to avoid any production use. We continue to develop new features and Virtuozzo 7 may contain serious bugs.

Q: Would it be possible to upgrade from Beta 1 to Beta 2?
A: Upgrade will be supported only for OpenVZ installed on Cloud Linux (i.e. using Virtuozzo installation image of OpenVZ installed using yum on Cloud Linux).

Q: How often you will update Virtuozzo 7 files?
A: RPM package (and yum repository) - nightly, ISO image - weekly.

Q: I don't want to use your custom kernel or distribution. How to use OpenVZ on my own Linux distribution? A: We plan to make available OpenVZ for vanilla kernels and we are working on it. If you want it - please help us with testing and contribute patches [2]. Pay attention that using OpenVZ with vanilla kernel will have some limitations because some required kernel changes are not in upstream yet.

vzstats in beta

For the last two weeks or so we've been working on vzstats -- a way to get some statistics about OpenVZ usage. The system consists of a server, deployed to http://stats.openvz.org/, and clients installed onto OpenVZ machines (hardware nodes). This is currently in beta testing, with 71 servers participating at the moment. If you want to participate, read http://openvz.org/vzstats and run yum install vzstats on your OpenVZ boxes.

So far we have some interesting results. We are not sure how representative they are -- probably they aren't, much more servers are needed to participate-- but nevertheless they are interested. Let's share a few preliminary findings.

First, it looks like almost no one is using 32-bits on the host system anymore. This is reasonable and expected. Indeed, who needs system limited to 4GB of RAM nowdays?

Second, many hosts stay on latest stable RHEL6-based OpenVZ kernel. This is pretty good and above our expectations.

Third, very few run ploop-based containers. We don't understand why. Maybe we should write more about features you get from ploop, such as instant snapshots and improved live migration.
