Thanks for the info, much appreciated!

Maybe a little off topic, but I am curious to know:  At the moment I find
it very convenient to go directly into a containers filesystem from the
hardware node - i.e. something like /vz/private/xxx/var/log/... etc -
 Would I be correct in presuming that by using ploop this will no longer be
possible?  I know I could just setup a test system and try it out but if
you know already it would save me some time ;)

Indeed, this is the only container on that filesystem and that physical
drive.  This time there were  no "spill over" but previous times when load
hit 50 or more the load  certainly did spill into other containers.

Best,
