I've run VMware Server (free, as in cost, not as in open source) on
CentOS to host WinXP VMs since it was in beta and have no complaints.
There is an RPM package available on VMware's site:
$ rpm -q VMware-server
It's only available in i386 package but installs fine on x86_64 and
supports 64-bit VMs provided the underlying hardware supports it. I
believe VMs are limited to a max of 2 processors each.
I've used VMware Server on systems varying from old AthlonXP, 512MB RAM
through to Intel Quad Core Q6600 with 4GB RAM. Note VMware will run on
older processors without hardware virtualization. In my experience
there's little noticeable difference between software and hardware
virtualization (on VMware), and each run at about the perceived speed
you would expect if it was on native hardware (I've not conducted any
benchmark tests). The main consideration is that you have enough RAM to
support the host OS (CentOS) and any VM(s) running on it.
I've not used Xen so can't offer a comparison.
