libvirt support for xm/xend *should* work, and there's also the libvirt libxl driver
written by Jim Fehlig from Novell/SUSE.

When you install libvirt it'll automatically create/start a bridge called "virbr0",
which is an host-internal bridge with "dnsmasq" running and configured to provide dhcp server
with private ip range, dns relay and NAT on that bridge.

So that's good enough for trying some VMs or running VM netboot installs.
