Yes. You'd pass in --virt-bridge0=xenbr1 to cobbler (or for a second 
interface, --virt-bridge1=xenbr1.

For --system, you have to define the virt-bridge values in cobbler now.

For --profile, you can specify it on the koan side, but you can only do 
one NIC that way.

Sure.

Hmm... point taken. I'll think about this some. Deprecating --virt-name 
in particular is probably not a good idea.
The main thing was to avoid duplicating a lot of cobbler logic in koan, 
which I really don't think it will be as complicated
as I originally let on :)
