Ok...  Hold the phone.  You just confused me.

KVM and OpenVZ are two different critters.  KVM is hardware
virtualization while OpenVZ is container virtualization similar to Linux
Vservers, LXC, BSD goals, Solaris Zones, etc.  The two are not related.
Are you saying that, in addition to supporting KVM, it also takes
OpenVZ?

For the record, I'm about to move the last of my installations of OpenVZ
over to LXC after getting burn on a couple of OpenVZ kernel upgrades on
RHEL 5.  It'll me LESS painful to upgrade the machines to RHEL6 and get
the VMs migrated to LXC than continue to fight with the out of
source-tree patches that OpenVZ requires.

Yeah.  If it's Linux on Linux then OpenVZ / LXC containers are
definitely the way to go.
