[Users] vzctl start yields err=-12

I'm honestly not exactly sure of the reason.

When I ran into the -12 error problem you're experiencing, I was applying
the ovz dostoevsky patch to vanilla centos 5.2, salgix 5.0.4 and debian
unstable (both with debian's stock 2.6.26 kernel and a vanilla 2.6.26
kernel).  I never received the kernel errors in openvz Bug 802 either but
tried the change mentioned in the bug report in the kernel build files and
it worked for me.

The problem seems to exist due to an inability in openvz (at least the
dostoevsky, it may be fixed in later releases) to utilise the fair
scheduling kernel profile in linux.
