Hi all,
I just recently started testing out oVirt in our lab. I’m using CentOS 7
on my hosts and using the hosted-engine model, and the oVirt 3.6
repository. I have NFS storage. I ran across what I think is a bug of
some sort, and I’m curious if anyone else has tried this or know what’s
going on.
I wanted to be able to expose the NFS server (not necessarily the share
used for oVirt storage domains, but other shares on the NFS server) to VMs
running on my host (currently my setup only involves a single host). I have
two 10GbaseT interfaced bonded together on the hose with two VLAN networks
on it currently, one for the management network, one for storage. When the
hosted-engine deployment was set up, I ended up with an ovirtmgmt interface
that was bridged to my infrastructure vlan interface (vlan 1080). So, I
added another network in my oVirt cluster named VM-Storage with vlan 1092
(my storage network). Here is approximately how I expected this to end up:
bond0 - (bonded interface)
- bond0.1092 (STORAGE - vlan interface)
- VM-storage (bridged interface)
- bond0.1080 (INFR - van interface)
- ovirtmgmt (bridged interface)
However, when I did network setup on the host, and dragged the VM-Storage
network over to the network interface and hit OK, the UI just froze, and
for a few seconds I checked on the host via ssh session and the VM-storage
bridge was setup, then the server just rebooted. After it rebooted, my
vlan interface was no longer there and it seems like both the hosted engine
VM and the host ended up being rebooted. In thinking about it, I may have
caused at least a temporary outage with my NFS storage when the new bridged
interface was set up which caused (maybe) the HA agent to think the hosted
engine vm went away or something, and that cause the reboots. Not entirely
sure, but this was certainly unexpected. I have tried several times and
the same result each time.
I did check that any other VM network with a different VLAN ID provisions
just fine on the host, so I assume there’s something that happens when this
storage network is provisioned that is catching oVirt off-guard somehow.
Anyone else have this issue before? Can I solve this by adding another
host, then moving the hosted-engine to a different host while I add the
storage network to each host?
Thanks.

Hi Kendal,
Please provide the logs from your host: Especially messages, vdsm.log and
supervdsm.log.
ovirtmgmt network is set as a VLAN network in Engine? ( a screenshot of
your network configuration on Engine may help)
Thanks,
Edy.
