Package: linux-image-2.6.32-4-openvz-686
Severity: important

This is a report of the kernel testing that I have conducted.
It worked better than I thought based on that the patch is newly
created.

Starting, stopping and similar operations works fine. But migration
do not. That could be because I do migration from an old kernel
version to a new one, but I assume that should work as well, right?
