Ok, we're ready for some testing.    It's simpler to use than I let on 
earlier.

For starters, --virt-bridge is now gone from koan.   It's much easier to 
set this in cobbler anyway.   The idea is to keep making koan simpler 
and simpler.   As a side effect of this, koan will no longer try to 
guess what bridge it should use -- it will use what you tell it, as 
obtained from Cobbler.

You can specify the bridge value in the cobbler settings file, in the 
profile (overrides the default in settings), or you can define it 
seperately for any NICs on a cobbler system (overriding the profile).   
So it basically works like any other parameter.   Yes,  you can use the 
same bridge for each NIC if you want.   Or any combination thereof.

I've tested multi-NIC systems on KVM and Xen alike, as well as 
profile-based provisioning with a single NIC.    mac addresses, ip's, 
hostnames, and other details
can be set on each NIC.    As indicated before that's as simple as 
--mac=AA:BB:CC:DD:EE:FF --mac1=AA:BB:CC:DD:FF:FF.   (Same for --ip1, 
--hostname1, and so on).

If you'd like to try this out (testing and comments much appreciated), 
you'll need to install both Cobbler and Koan from git (the versions 
should be 0.6.3-1).
I would recommend backing up your /var/lib/cobbler/* first -- in the 
future, the RPM will likely do this for you.

Note:   I have yet to update the Web UI to support multiple NIC editing 
-- it should mostly be able to edit the first NIC, but not the others.  
That's next up on the list (along
with finally paying attention to --virt-cpus).

Hopefully this works like everyone wants, if not, let me know.

Today I also corrected a bug in the WebUI where it wouldn't authenticate 
under EL4.   That's fixed if anyone is interested.  Patch here:
