I use Xen to do my virtualization stuff. It supports both running fully
virtualized like KVM, or paravirtualized. Linux kernels support the
paravirtualization, and that can result in faster networking and IO in
certain situations. It is opensource and free. Debian has packages for
it, not in fedora yet. All of the distros support running as a
paravirtualized guest, but it's reccomended to use a specific kernel so
you can pause the vm.

Not quite as simple to set up as virtualbox or vmware, and I've never
used KVM, but I really like xen.

It's running 10 vms, one of which handles asterisk and mail for a
friend, and mine are various for databases, email, web servers, and
other purposes. I've found it works wonderfully.
