Of course, there are some situations where OpenVZ (ie OS Virtualization) isn't suitable... but for the vast majority of common server tasks, it is. I don't claim you should try that many virtual machines on a single host node but it just goes to show you the density differences possible between Xen and OpenVZ, eh? :)
apart from mass scale hosting solutions, I am yet to see a role where openvz actually provided a better all around VM solution than Xen. Even the management tools and the developer support behind Xen far out weights that on openvz.
And for those mass hosting solutions, a bit of security minded setups would remove the need to have this sort of a virtual userspace virtualising anyway. ( in a lot of the cases )
