[PVE-User] Moving from XenServer to Proxmox... slowly

Here we user as third|quorum machine, a VMWare machine. It worked 
perfectly as far as it does not host any VM itself.

To migrate linux machines, we created a new VM on proxmox, booted it up 
with a sysresCD and then  netcat the whole system from the xen VM to the 
new PVE machine.

Hope it helps,

The rest of my servers are Ubuntu based, and PVM's so I'll need to add a kernel, so I'm looking at http://www.blog.turmair.de/2010/12/xen-to-kvm-or-physical-vmware-migration/
