You should always use mailing list. It's very counter-productive otherwise.

The commands you look for are:

vzctl chkpnt $VEID --suspend # this freezes container
vzctl chkpnt $VEID --dump --dumpfile /some/path/to/dump/file # this 
dumps the container that was previously frozen
vzctl chkpnt $VEID --resume # this un-freezes the container

So this sequence helps you to do what you want without a need to restore 
from a dump file,
and should be way faster
