We are moving to Proxmox in favour of raw OpenVZ for container support; so far
this has been a strict win.  I wish I could fund faster development of their
HA support in release 2.0 for OpenVZ containers as well as KVM. :)

In any case, KVM does OK for testing but we have not put it into production.
However, I don't see any great reason to suspect it will do worse than the
"hosted" versions of VMWare and co.
