I don't know, but I would consider the real competition to be between
OpenVZ and libvirt/KVM - I don't think Xen is going anywhere in the long
term.

KVM supports the use of kernel-same-page-merging (KSM), which OpenVZ
doesn't (yet?).  For some applications KSM can be a big win...

We currently use/support both OpenVZ and kvm.
