Would that statement apply to other hypervisors like KVM, VMware ESX or Hyper-V, i.e. are the deficiencies in PCI devices/firmware, IOMMUs, platform firmware?  

If the statement is Xen specific, are there specific issues or known sections of Xen code that would benefit from a rewrite or redesign inspired by other hypervisors?
