A small script can do it for you and will not interfere with NM 
operation (AFAIK - works for me).
Attach the NIC to the bridge.

If the VM is a /client/ and originates all connections, you don't need 
tap, and the outgoing IP will be the host, doing masquerade.

Not that I can see, I have three servers and several test machines on a 
single bridge and it works fine.

Also: I have done this on FC{6,9,10} but not FC11 yet, I simply don't 
have an extra machine with hardware VM which I can use at the moment. I 
lack the courage or need to try KVM under KVM.
