[CentOS-virt] redhat's Qumranet acquisition

My experience has primarly been with Xen.

I have helped a company successfully deploy Xen on CentOS. They had
a really nice cobbler setup and were able to leverage it nicely to make
the transition to virtuals easy.

They found our running xen book (http://runningxen.com) a great resource.

Another factor to consider is the application workload and the guest
requirements.

Over the last several years, we at Clarkson, have done a lot of
performance studies
on virtualization systems (as well as writing the book on Xen).

You can find links to much of this work at:

Hope that helps,
Cheers,
Todd
