The loads of domU's have no relation to the load of dom0; they are separate VMs. dom0 is not running the VMs. It's the hypervisor that's running the VMs (dom0 + all domU's) and the load if each VM is local to that particular VM. In your case, dom0 is lightly-loaded (as it should be), while the single domU is heavily loaded. Check first what's causing such heavy load: not enough RAM making the system swap-thrashing? Overzealous polling by spinning? Buggy kernel? Rgds, Just to be clear, are you saying the CPU usage of the host OS does not reflect the overall CPU usage of the guest VMs it hosts?
