Plus, as far as I remember there was a patch somewhere on download.openvz.org or sysctl which allows to hide non-root processes from root VE.

I know I'm a bit offtopic here, but taking in example solaris 10 with
it's zones, it's possible to supply
ps with "-Z" command , which will say what zone/container process
belongs to. Would be nice,
to somehow label container processes with container ID in kernel and
have userland (ps for example, or any other tool)
to be able to show this label.
Thanks.

There are tools vzps and vztop which does that.
vzps ax -E <VEID>
will show tasks from specified VE only (and for -E 0 it will show host system tasks only filtering out containers).
Thanks,
Kirill
