Wow. Sorry almost missed that thread.
2.6.32-openvz-budarin.1 does not contains any specific patches for ext4.
So it is probably memory corruption caused by ovz stuff (2.6.32 is still
experimental), or you caught unknown bug, the later it very unlikely because
"cp" is very popular cmd :)
I'll try to reproduce your issue.

That's not true, root/$veid is just stacked filesystem on top
of private/$veid.
