No.

On the other hand I can tell you what I did, a better way to do it (which I 
didn't know when I started), and it should get you started. You may have joy 
from virt-manager, it's on my list of things to try when I have time to look at 
better solutions to problems to problems for which I have an ugly working solution.

The secret is to have your NIC attached to a bridge on the host, and use that 
for networking. So instead of having eth0 be your device for default route, you 
have the bridge, and the physical bridge is attached to the bridge. Now you can 
use either a fixed IP or a known DHCP assigned IP for your virtual machine.

I have:  NIC(eth0)---[bridge(br0)]---default route

Start the kvm machine with: "-net nic,macaddr=$MAC -net tap" to do DHCP IP 
assignment, or "-net nic -net tap" to use a static IP or random IP from DHCP.
I run my own DNS, DHCP, mail, http, so I can control everything, but you may not 
wish to do so.

The better way: I have seen posted the suggestion that you name the NIC "peth0" 
and the bridge "eth0" to make the default Fedora firewall and routing work. 
Haven't tried it.

Hope this gets you started, I read the kvm list and I just beat on it until it 
worked "back when" without much doc, and haven't changed anything.
