Hi Giorgio -

Unfortunately, I don't actually have any infiniband hardware to test with in my lab. I'm not even sure anybody on the Node team knew there were IPoIB use environments. That's great news (for 3.6)!

oVirt Node Next is much closer to "plain" RHEL. This sounds like it may be a bug in ovirt-host-deploy, but it may also be cockpit.

Can you be more specific about where you're seeing this issue? Adding a bridge from cockpit, adding a hosted engine node, or registering the node to engine?

Hello list,
currently I have an up and running Ovirt 3.6 installation where every hypervisor
access the data domain via NFS over infiniband. All is working as expected, with
a couple of hooks I can set connected mode on ib0 and an MTU of 65520.

Now I'm testing Ovirt Node Next, but the behavior is different. When I try to
set up host networking the procedure attempts to bridge the network "ibstorage",
defined in Networks tab, with ib0 interface but a non ethernet interface cannot
be bridged that way.

There's any way I can obtain the desired result? Or somehow tell to the
hypervisor to not bridge that connection and to use ib0 directly?

Thanks
