Hi, I''m trying to get a domU to make use of all the processor power available on a Dual Xeon server; as far as I can tell, Xen 3.0 has support for multiple CPUs in virtual domains. How do I setup the configuration so that a virtual domain utilizes both physical CPUs on a machine?

Pinning can be used to restrict this, by ensuring certain VCPUs can only run on certain physical CPUs."
