True, xenstored is more a victim of dom0 load than a cause of it. We've
seen some pretty nasty performance when trying to boot lots of VMs with
a loaded dom0; PV drivers in the VMs could block for many seconds
waiting for xenstore to get back to them. It still makes sense to get
it out of there.
Cheers,
Tim.
