In Xen's 3.0 documentation is stated:

"f 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."

I am mostly running web servers, so it's IO intensive.

But I cannot find from the documentation how to actually accomplish this?

From RHEL5-beta documentation I found xm commands how to accomplish
this in running domains, but this should be set in the config file so
we can do the pinning everytime the guest boots, right?
