There have been reports to the FreeSwitch crowd of successful 
implementation on Xen and OpenVZ.  Apparently the performance is 4x that 
of Asterisk and so the problems running Asterisk on a container do not 
affect FS as much.  The Sangoma folks have also gotten the wanpipe 
drivers to play with Xen so you're not limited to SIP but can have POTS 
support also.  There's work being done to try to get it working with 
OpenVZ and since it works fine with Xen, I don't anticipate problems 
with a OpenVZ.  Personally I haven't gotten it to work yet, but others 
are working on it also.
