Hi,

i've tested the openvz kernel from url:
http://charm.itp.tuwien.ac.at/~mattems/linux-image-2.6.32-4-openvz-amd64_2.6.32-10_amd64.deb

and from the git release:
commit 6d267858ed5a189626b4c85fdb30642c01f8aa49

on a amd64/64bit with the vzctl/vzquota from git:


1) on fist boot, w/o running vz-subsystem:
