Since we're on the topic, I thought I'd pipe up for Steve's benefit 
about a small matter which I found baffling for a few days...

If you run "df -k" in a VE, you will often get a different answer than 
vzquota. This is because vzquota doesn't keep to-the-moment statistics 
in its cache file. You must run "vzquota stat VEID" in order to have the 
cache updated; then vzquota will report the correct usage. This is in 
the Wiki, but I thought to save you some time. :)
