RE: [Xen-users] VCPUs with many (20?) domains

Yep. VCPU 0 will take a huge it for I/Os as they are not well balanced. So just 
make sure you balancer all your VPCU 0s on as much physical CPU as you can.

Unless you have huge needs for processing power into domUs, I'm not sure you'd 
benefit from 4 VCPUs par server. Having two of them would balance I/O on VPCU 0 
and processes will still be able to run in parallel on VCPU 1. Could be a nice 
deal.
