I have recently put virtualized xen CentOS host and guests into
production, using the standard tools in CentOS 5 and all works well.
Not sure about the VMServer since I haven't tried it, but with xen
built into the kernel and what I've seen of the tools such as
virt-manager, virt-clone, virt-image, it is very light and simple and
should work well for the needs described.

In in this case, I'd suggest formatting the whole disk, with a very
large partition to hold xen image files, files that represent the
hard-drives of the guests.  While disk io in the guests is a bit
slower, the flexibility should be worth it, as imaging a guest is no
more difficult than a file copy.  The guests can access the host's
storage via NFS or Samba just as an networked host can.
