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 :)

Thank you,
