The current stable branches are RHEL-4 2.6.9, RHEL-5 2.6.18, and vanilla 2.6.18.  Rumor has it that the Parallels folks are working on 2.6.27 as the next target stable branch but we'll see how that goes.

As a result the OpenVZ project has a repo of Debian packages.  If you want to use Debian on your host node I'd recommend using the packages provided by the OpenVZ project.  You can find info here:

Debian has vzctl version 3.0.22 for their upcoming release. But I want 
to avoid upgrading the whole system to a beta state. The kernel I am 
using, 2.6.26, is from Debian backports, i.e. it's backported from the 
upcoming release to the stable one ("Etch"). There is a special openvz 
package for this kernel, so I would have expected that it works together 
with other packages from "Etch".

For reasons explained below, I decided not to use the .deb packages 
mentioned in the OpenVZ wiki. I got all virtual machines running (manual 
config), and I will use vzctl only to enter a machine.
So the question is: Are there any problems to expect while just running 
OpenVZ with the 2.6.26-bpo.1-openvz-amd64 kernel I am using?

I'm stuck to Debian because a migration to another distro would cause 
significant downtime, and I have no hardware to use temporarily. The 
kernel packages mentioned in the Wiki are packaged in March and May, 
resp. I prefer packages that are maintained more frequently (for 
security updates etc.).

Thanks for your help, Scott.
