Hi,
Little over a year ago Fedora introduced alternative bonding driver
for network devices - libteam: https://fedorahosted.org/libteam/
Can we expect libteam support in ovirt at the same level as for "bond"
driver? Currently, libteam bonded interfaces are not visible in
"Setup Host Networks" dialog.

Hi Tomasz,
We are aware of libteam bonds and I personally look forward to them very much.
The ideal way to support them would be via one new network configurator that
would implicitly make teamd bonds instead of usual bonds. After the iproute2
configurator is finished (it is currently in progress but quite functional) it
should be quite easy to inherit from vdsm/netconf/iproute2.py and modify
configureBond, removeBond and editBondings so that they make use of teamd bonds.

What needs to be done to get ”minimal” support? By minimal I understand
oVirt acknowledging that network interfaces are teamed. Configuring teams
from oVirt can come later. Right now teamed interfaces are displayed
as separate in net configuration dialog, and master team device is not
displayed at all. I could live with manually configure teams if only
I can attach them to ovirt networks.

would that be a bridged or a bridgeless network? A vlanned or non-vlanned
network?

I'm not entirely sure if you honestly asking or just trying to make me
realize how many variables are involved in such support. I will assume the
former.
I have team0 interface of two physical NICs. I'd like to have this team0
interface attached to particular VM. That would mean bridged network I suppose.
There are no VLANs in my setup.
To be clear, I am able to tear down this setup and revert to old-school bond.
I'd prefer not to – it needs some downtime to reconfigure and validate.
So now I'm against the question: what will require more work from me,
reconfiguring network or making ovirt recognize basic team0.

I'm not entirely sure if you honestly asking or just trying to make me
realize how many variables are involved in such support. I will assume the
former.
I was asking because if it were non-VM network it could have been easy to put
up a hack to do it.
I have team0 interface of two physical NICs. I'd like to have this team0
interface attached to particular VM. That would mean bridged network I
suppose.
Hacking around attempts (not actually tried)
=============================================
Well, I guess that what you could do is to configure the whole network manually
create the bridge and add team0 to it manually, then craft the ifcfg files for
them. Then create the libvirt xml definition for the network over the bridge.
After that maybe the engine will pick up the network as defined in the host and
let you start VMs with it.
Another thing that might (just might) work would be to use the engine to set up
a vm network overt a normal bond and then just use brctl to replace bond0 for
team0 on that bridge. This would save you from the libvirt network definition
(you should remove the bond from the bridge in ifcfg files as well).
However, in both options, you might have the issue of the engine detecting the
configuration as out of sync.
There are no VLANs in my setup.
To be clear, I am able to tear down this setup and revert to old-school
bond.
I'd prefer not to – it needs some downtime to reconfigure and validate.
So now I'm against the question: what will require more work from me,
reconfiguring network or making ovirt recognize basic team0.

In the end, the best thing would be to request a feature for team support. It would
entail making netinfo able to report team devices as bonds and inheriting from some
configurator (it could be done entirely on vdsm side).
