NetworkManager does not support bridging, but it is not technically
neccessary to disable NM completely. You merely need to disable it
for the particular network cards you wish to bridge. You can do this
by creating an ifcfg-XXX file for the NIC in question and adding the
and then networkmanager will ignore that.

You should never have to worry about tap devices at all. libvirt takes
care of all tap device creation. The only manual config you should ever
need todo is to configure a bridge device as per that wiki page above.
In Fedora 12, we will hopefully be able to do this from virt-manager
