RE: [Xen-users] bare metal xen hypervisor
The Dom0 has direct access to hardware, so in general IO operations should be
faster (better latency). DomUs access to hardware is provided by hypervisor
using Dom0 - so the bits have "longer" way to roam out of the VM to real
hardware.

That´s a new information for me.
Does that mean that the performance of processes in Dom0 ist not better or
worse than those in any DomU?
I thought that Dom0 processes have a better latency and general performance
compares to those in a DomU.
