yesterday i spent several hours installing openvz with the result that it does not seem to run on my machine - a VIA EPIA V10000 running a VIA C3 at 1 GHz.
(As soon as i switched the system, a debian sarge base installation on an XFS file system) extended by Thorsten's debain packages for openvz to one of the ovz-kernels, the system became unstable: the ovz tools could not find their files although the configuration data was correct, even worse, after a "su - another_user" that User's shell could not access anything in its search path.)
