Actually, Xen and VMWare can both do full virtualization (hypervisor
unaware guests). Xen also does paravirtualization (hypervisor aware
guests). VMWare has more commercial tools, but they all run on windows
as of today. Xen has (imho) faster to implement tools, but they aren't
as polished as VMWare.
I think that for the less linux saavy, VMWare is the way to get
started. If you are well versed with making and restoring linux disk
images and networking, then Xen is for you. They are both great, but
require lots of R&D (tinkering) to get what you want.
Don't pay attention to marketing claims of performance or scalability.
The truth is that if you have a high-resource/load host, it's going to
be the same on a hypervisor. The way to virtualize is to combine many
(5-15) low-load hosts onto one hypervisor host.
Hope this helps.
