Hi,
you cant bridge infiniband. You have to set the network as "no VM network" so it will not be bridged.

I have a similar setup where Infiniband is used for data domain mount and vm migrations and to have it working in connected mode with a MTU of 65520 you also need a couple of vdsm hooks on all the hypervisors.

Regards

We are starting to scale and have started to notice the limitations of using the
default network for everything.  We have infiniband in our vm hosts and would
like to use that as our migration network, but haven't figured out how.
Creating a logical network and assigning it to one of the infiniband networks
doesn't seem to work because infiniband doesn't handle bridging well.

Regards,
Logan
