Debian kernel packages

Good news, everyone!
Prof. Farnsworth


Many people use OpenVZ on Debian. In fact, Debian was one of the distribution that come with OpenVZ kernel and tools. Unfortunately, it's not that way anymore, since Debian 7 "Wheezy" dropped OpenVZ kernel. A workaround was to take an RPM-packaged OpenVZ kernel and convert it to .deb using alien tool, but the process is manual and somewhat unnatural.

Finally, now we have a working build system for Debian kernel packages, and a repository for Debian Wheezy with latest and greatest OpenVZ kernels, as well as tools. In fact, we have two: one for stable, one for testing kernels and tools. Kernels debs are built and released at the same time as rpms. Currently we have vzctl/vzquota/ploop in 'wheezy-test' repository only -- once we'll be sure they work as expected, we will move those into stable 'wheezy' repo.

To enable these repos:

cat << EOF > /etc/apt/sources.list.d/openvz.list
deb http://download.openvz.org/debian wheezy main
deb http://download.openvz.org/debian wheezy-test main
EOF
apt-get update


To install the kernel:
apt-get install linux-image-openvz-amd64

More info is available from https://wiki.openvz.org/Installation_on_Debian and http://download.openvz.org/debian/

Are you going to support ubuntu-server as well? As far as I know this very distro has gained rather wide popularity among system administrators who prefer rich by default software which RHEL or CentOS can't boast.

For your OpenVZ host node you don't really want extraneous software installed nor unneeded accounts. That's the general rule for all virtualization product hosts. Not having a enormous package library for the host node is NOT something I'd consider a problem.

Kernel for wheezy should work on Ubuntu (or so we hope). Have no time to test it :-/

Personally I have no difficulties with using the latest OpenVZ's kernels with Ubuntu Server. What's more annoying though is user space…

Well, maybe we need to set up a few CTs for building the userspace for Ubuntu. What version are you interested in (I suppose it's 12.04 since it's LTS)?

Correct — cat /etc/issue.net
Ubuntu 12.04.2 LTS

Actually I answered your question but my peaceful answer was marked as SPAM. ;)

While I haven't been keeping a close eye on it, I do believe the number of Debian and Ubuntu host nodes has increased quite a bit since this action and I only expect that will continue.

I see only "linux-image-2.6.32-openvz-042stab081.3-amd64_1_amd64.deb". Wheezy has kernel version number 3.2.

This is what my next blog post will be about (explaining why the number is 2.6.32). In short, this is the right kernel, go ahead and use it.

I thought, Ubuntu LTS will be best select for OpenVZ HWN. Debian life cycle is so short for virtualization platform.

The best is Red Hat Enterprise Linux (or CentOS). "Red Hat Enterprise Linux 5 and 6 are offered with 10 years of Production Phase support, followed by a three year Extended Life Phase" (https://access.redhat.com/site/support/policy/updates/errata/

We are doing it for Debian mostly because OpenVZ kernel used to be a part of official Debian releases, and now it's not so. Besides, this repo should work for 12.04 LTS (although I haven't tested it).

Hi,

Is there any chance on the .debs provided that we can get JFS enabled in the Kernel as it ships enabled in Debian 3.x kernels and even in the 2.x branch kernels as well?

Re: vzctl ploop support
Yes, sure. It's the same code.
