I use Xen personally and at work I work with VMware. I don't have any
machines personally that have hardware virtualization extensions in the
processor, so I'm only doing para-virtualization with CentOS 5 as host
and guests. Documentation seems a little sparse if you want to deviate
from the default configuration too much in Xen. Other than that I've
been very happy with Xen.
At work we've been playing with VMware Infrastructure 3. If you are
going to go the VMware route, this is by far the best bang for your
buck. You are able to manage several VM hosts under one interface, and
if you are running Windows as a guest you can do some pretty neat things
(coming soon for the Linux side). I've also used the free version,
VMware Server (also called GSX, Infrastructure comes with the version
called ESX) on both Windows and Linux...prefer using Linux though as the
host (much better stability and low-level options if you are into
customizing the environment).
Any more questions, like specifics, please ask. I've been using Xen and
VMware for several months now.
