Is running pve inside openvz possible?

It just came to my mind, maybe it is a stupid question, but is it possible? I know I can install pve in kvm guest, and I did it a few times for testing, but since pve over wheezy is supported, is it tecnically possible install pve over openvz debian container, and if not why, what is missing or incompatible? Just to know.

Thanks,
Marco
