Is it 3.5.0, 3.5.4, 3.5.5? or doesn't matter and the issue is in the VDSM 3.6 side (and therefore the 'version' field should be 3.6) ? Please provide engine version, engine.log, and {super,}vdsm.log. The currently-attached ovirt-host-deploy.log shows no failure afaict.
Did you test this flow in 3.6? does it work? reproducible, adding 3.6 host to rhevm-3.5.5-0.1.el6ev.noarch by removing 'ovirtmgmnt' bridge and adding correct 'rhevm' bridge on host will enable 3.6 hosts inside 3.5.5 engine The issue is in bridge through which vdsm connects to hosts. In older version of RHEV-M we used rhevm bridge as a default network connection. In oVirt and RHEV-M-3.6 we use ovirtmgmt bridge. As during host deployment vdsm is unable to attach rhevm bridge to the correct network interface (as it has already a ovirtmgmt bridge) it fails on setup. Previously I saw some bugs in the past about resolution of default bridge naming, as it should have been moved to ovirtmgmt in oVirt as well as RHEV-M. Do you know what was the resolution in this issue? If we are using different network bridge for oVirt and RHEV-M or it was decided they will be the same? What has created the ovirtmgmt bridge on your host? We do not support adding a host with one management network name into a cluster with another name. Please confirm that prior to deployment, no bridge existed on the host.

The environment was used for a different scale bug, and is no longer available.

The environment was used for a different scale bug, and is no longer available. ovirtmgmt bridge on host was created by 3.6 engine where host was previously added Problem is we have different bridges for rhevm-3.5 (rhevm) and rhevm-3.6 (ovirtmgmt). As mentioned in comment#5 these steps works, so the issue is only in the name of bridge: 1. Remove host from 3.6 engine 2. Remove ovirtmgmt bridge from host 3. Add host to 3.5 engine (which will create rhevm bridge) (In reply to Lukas Svaty from comment #12) > Problem is we have different bridges for rhevm-3.5 (rhevm) and rhevm-3.6 > (ovirtmgmt). The default bridge name has intentionally changed in 3.6. Cf. bug 1204793. I agree that this indeed is not a but, but by design behaviour, so we will be able to move hosts from ovirt to rhevm and so on. |
