If you are using recent versions of Fedora, you might want to look at
KVM as it is has native support. Xen is a great hypervisor, but it
currently requires more effort to get working. If you want to use Xen
"out of the box", then I'd recommend looking at CentOS 5.5.
Both KVM and Xen support hardware virtualization.
