> Has anyone done any analysis of cache coherency on SMP systems > with Xen? Since we currently don't support SMP guests there's very little sharing of data between CPUs. Xen itself is quite small there's very few data structures that aren't per-CPU. > Can processor affinity be set to associate VMs with specific CPUs? Yes, VMs are currently pinned to specific CPUs (see xc_dom_control pincpu). It would be easy to add a periodic VM re-balancer. It could even be protoyped in user-space in domain0.
