Re: [Xen-users] Bug or cofiguration error?
I'm getting the impression you're confused about what dom0 actually does; Xen is a Type-1 hypervisor, meaning DomUs don't run "in" dom0, and dom0 is really just another VM, albeit one with special privileges. You cannot use "standard" linux monitoring tools in dom0 to find out usage of host resources, since those tools will only show you what goes on within dom0, and as stated above, dom0 is just another domU along with any other domUs that happen to be running on the host. CPUs don't have to be available or online in dom0 for the hypervisor or other guest domains to put them to use. To see the actual host resource usage, you need to use the XCP management commands or xen-aware monitoring utilities like xentop.

This affects the performance? Because mpstat shows the cpus 4...15 isn't used.
