[Andrew Woodward <xarses@xxxxxxxxx>]

For one, if we are building this with the system tests, there is no
hope of it working when we apply bonding to each interface with
underlying "management", "public", "storage", "private" roles from
libvirt, at minimum, we need to set eth1-4 to the same role in
fuelweb_test/settings.py or override it with a new SetupEnvironment
instance.

However, after fixing this by hand we still cant get the bond to pass
traffic in the bond correctly when using any of the balance modes, and
LACP wont ever work with out a real switch. We have confirmed that
active/backup works fine in CentOS.

We think that the balance modes probably wont work because of libvirt
and linux birdges probably don't support it.

We are moving to testing balance mode on real hardware.

On a related note, I thought we added support to move the Admin (PXE)
Interface, but it's locked in the UI, is this expected?
