You can't just post numbers without the data to back it up, especially when it conflicts greatly with the Xen developers statements. AFAIK Xen is well on it's way to inclusion into the mainstream kernel.It doesn't matter. The proof that Xen has more overhead is trivial Xen does more, and Xen clients don't share resources well.
I understand the difference. It was more about Kirill grabbing numbers out of the air. I actually think the containers and Xen complement each other very well. As Xen is now based on 2.6.16 (as are both VServer and OVZ) it makes sense to run a few Xen domains that then in turn run containers in some scenarios. As far as the last part, Xen doesn't share resources at all :)
