Good point. We need a "standard" criteria on what a "best practice" is :D

As far as dedicated dom0 CPU goes, there's this entry from
http://www.cl.cam.ac.uk/research/srg/netos/xen/readmes/user/user.html

"If you are running IO intensive tasks, its typically better to
dedicate either a hyperthread or whole core to running domain 0, and
hence pin other domains so that they can't use CPU 0. If your workload
is mostly compute intensive, you may want to pin vcpus such that all
physical CPU threads are available for guest domains."

Since in my environment I/O (disk and network) becomes the bottleneck,
it's a best practice for me.
