First, the thing you need to check is not what free shows -- look at the 
appropriate line in /proc/user_beancounters.

What free shows is some kind of approximation, and if it doesn't work 
right away first check that vzctl version you use in both cases is the 
same. Then check for 'meminfo' setting in VE config. Then report a bug 
to bugzilla.openvz.org
