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

[Gerald Brandt]

Hi,

I'd considered that, but I'm having trouble finding a system that supports VT-d/VT-x.

Any hiccups converting Xen to KVM?  I imagine the Windows boxes will move easily enough, just using clonezilla or similar.  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/

Any performance issues?

Gerald
