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.
