I had a longer talk with the proxmox folks back then when
proxmox was new and innovative, and we came to the conclusion
that there is no technical reason why proxmox shouldn't
support Linux-VServer and they told me that they plan to
do so in the 'near future' ... I guess they got an offer
they couldn't resist locking them in.

Xen was a nice idea to implement the conecpts of high
end PowerPC hypervisor systems on low end PCs, but IMHO
it has never really taken off and was replaced by kvm
which IMHO is a lot simpler to handle from the admins
point of view.
