Infiniband should not be bridged. Ovirt tries to build a bridge over a NIC if the network is a VM one. Please verify that it isn't. On Mon, Jul 4, 2016 at 5:10 PM, Giorgio Biacchi wrote: > As I said, Infiniband is not ethernet so it cannot be L2 bridged. This is > normal >

As I said, Infiniband is not ethernet so it cannot be L2 bridged. This is normal and I understand why it can't be done. I'd like to know if there's a way to configure host networking for infiniband link without bridging because is not necessary to have a bridge there. In addition to this, 3.6

Hi list, I'm trying a test installation of the new Ovirt Node Image and engine before upgrading my 3.6 installation. In my current environment every hypervisor access the NFS shared data domain via infiniband. With a couple of vdsm hooks I was able to set the infiniband link in connected mode and
