I can only highly recommend against using the debian openvz kernels. I
always had stability problems with them and a few months ago I
discovered a major bug (
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=655385), causing the
whole system to get instable/ freezed.

For a few months now I'm using the official rhel6 openvz kernels and
convert them into debian packages as described here:
http://wiki.openvz.org/Install_kernel_from_RPM_on_Debian_6.0 Since then
I never had any problems again so far :)
