openVZ is much more like a freebsd jail, all the guests have to run the same kernel as the host.
with a xen PVM you can run any kernel you want, as long as it's recent. in HVM mode (using QEMU for full emulation, with VT-x, etc) you can run guest OSes totally different from the host OS. I have a cacti install that is CentOS 6 amd64 running inside a Debian-testing amd64 host. fault tolerance, you can use the underlying filesystems of the LVM containers to keep a virtual guest disk cloned for hot standby to a second totally identical hardware platform.
