Xen virtualization is included as part of CentOS 5. Xensource's XenServer Exoress Edition, so far as I can tell, hasn't changed at all since Citrix took them over - dual-socket with upto 4GB of RAM, and four virtual machines. What does XenSource's product have to do with CentOS.
Regarding VMware, are you talking about the free VMware Server or the very expensive VMware ESX/Infrastructure? If the former, there is a lot more overhead with VMware Server when compared to Xen but VMware Server will allow you to run unmodified OSes... whereas Xen requires VT hardware support in the CPU to create fully-virtualized aka unmodified OSes.
If you are wanting to run Linux on Linux, I'd recommend you look into OpenVZ and/or Linux-VServer.
Oh, and while I'm here, I'll plug my recent interview with the Linux-VServer project leader:
