I'm going to run two servers with OpenVZ on Wheezy. Since there are sadly no OpenVZ kernels in debian anymore I want to use the Proxmox kernel instead.

I'm doing all replication with scripts I have already in place. What I don't want is all the pve cluster stuff which in my case only gets in the way.

But if I try to install vzctl I get the whole pve cluster stuff if I want it or not.

How can I install only the proxmox kernel without it?

EDIT: Which packages do I need from proxmox and can I mix them with the wheezy packages? Does vzctl from Wheezy work with proxmox kernel? How can I make shure to only get the packages I need from proxmox and not the ones I don't?

This is untested, but seems like a fairly simple solution.

Add the repos:

nano /etc/apt/sources.list
+ deb http://download.proxmox.com/debian wheezy pve-no-subscription

Download the kernel image and header.

apt-get update
apt-get install pve-kernel-2.6.32-28-pve pve-headers-2.6.32-28-pve

Remove the repos:

nano /etc/apt/sources.list
- deb http://download.proxmox.com/debian wheezy pve-no-subscription

If you need to dig around for updates to the kernel, and forgot the naming convention they were using, you can just check the repos online, or use an apt-cache show.

ProxMox repo: http://download.proxmox.com/debian/dists/wheezy/pve-no-subscription/binary-amd64/

  • I think that package pinning may be a better idea than removing the repository after installation, that way you would still be able to get updates.

  • Agreed. If I have some more time later I might look into updating this.

  • Meanwhile I found out that the 3.0 version of vzctl which comes with wheezy is to old for the kernel. So you have to find a different solution. Mine was to use the kernel from openvz.org.

    I'm still crossing my fingers that proxmox will implement lxc support, alas, they seem to be more red-hat oriented.

Largely taken from here:

Get the latest kernel and utils. You need

vzkernel
vzkernel-devel
vzctl-core
vzctl
ploop-lib
ploop
vzquota

vzkernel-devel is optional.

cd /tmp
wget http://download.openvz.org/kernel/branches/rhel6-2.6.32/042stab076.8/vzkernel-2.6.32-042stab076.8.x86_64.rpm
wget http://download.openvz.org/kernel/branches/rhel6-2.6.32/042stab076.8/vzkernel-devel-2.6.32-042stab076.8.x86_64.rpm
wget http://download.openvz.org/utils/vzctl/4.3.1/vzctl-4.3.1-1.x86_64.rpm
wget http://download.openvz.org/utils/vzctl/4.3.1/vzctl-core-4.3.1-1.x86_64.rpm
wget http://download.openvz.org/utils/ploop/1.7/ploop-1.7-1.x86_64.rpm
wget http://download.openvz.org/utils/ploop/1.7/ploop-lib-1.7-1.x86_64.rpm
wget http://download.openvz.org/utils/vzquota/3.1/vzquota-3.1-1.x86_64.rpm

Install the following packages...

apt-get install fakeroot alien libcgroup1

... and convert the RPM packages to DEB packages:

fakeroot alien --to-deb --scripts --keep-version vz*.rpm ploop*.rpm

Install the DEB packages as follows:

dpkg -i vz*.deb ploop*.deb

If you're having problem about overwriting files from other packages, try adding --force-overwrite option.

Make OpenVZ load on boot:

update-rc.d vz defaults
update-rc.d vzeventd defaults

  • I think this is the link you meant: howtoforge.com/… (Your link is the Squeeze Howto.) But this doesn't solve the problem of installing the Proxmox-Kernel and tools.

I ended up not using proxmox at all.

While I was trying to install proxmox the people at openvz decided to provide their own debian kernel which is - like the proxmos kernen - a repackaged RedHat kernel. This is bundled with all the needed tools and all you have to do ist add:

deb http://download.openvz.org/debian wheezy main

to your sources list.
