They're both collaborating on getting containers support into the 
kernel so they can co-exist. 

I've used neither OpeNVZ of VServer, but there was a rather striking
presentation at OLS  - in the tests performed VServer was the top
performer across the board and OpenVZ had a very bad showing.

This is probably too early to be useful for anything in real world. The
network device virtualization isn't finished, and there's no work on
device virtualization, so any container can access pretty much anything
on the parent OS. Thus far is basically just PID, filesystem and UTS
namespace separation (as of 2.6.26)
