Indeed, this is fine as a temporary workaround :-)
FWIW, using koan --display seems to imply that the MAC address isn't
getting sent by Cobbler.

I'm actually using unpartitioned LVM volumes for my guests :-) So the
above uses the pre-created /dev/data/test and /dev/data/swaptest LVs.
My tests have shown better performance that with files.
I haven't tried not having the LVs pre-created and using
"virt-path: '/dev/data/$name,/dev/data/swap$name'" with
"virt_file_size: 4,2", but I suspect it won't work :-)

This will basically add one layer of configuration for very little to
no gain in my case. I can live with that and do understand that the
line must be hard to draw between inherited profiles and systems.
It does seem like the WebUI doesn't currently know of inherited
Thanks for all your help :-)
