Here it is: http://cloud.apra.it/index.php/s/4cdcde8cafdb7a1c2c2374b02dce118e

I tarred all the agent.log on both servers.

The engine was running on kvm01 and got shutdown on kvm01 around 10:35 AM on 29 November. But I think that's not the problem, it is supposed to shut down if the host can't reach the gateway. Probably the nic problem was already there but got triggered on reboot

Btw I kept digging: I extracted the ovf from which vm.conf is generated:

ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(getEngineVMOVF) OVF_STORE volume path: /rhev/data-center/mnt/blockSD/2c3585cc-b7bc-4881-85b3-aa6514991a26/images/9c5e2121-f1a3-4886-964c-c74fdfbbb3c1/ff765055-09c5-4b05-9cc7-5277b15c5d08

# tar xvf /rhev/data-center/mnt/blockSD/2c3585cc-b7bc-4881-85b3-aa6514991a26/images/9c5e2121-f1a3-4886-964c-c74fdfbbb3c1/ff765055-09c5-4b05-9cc7-5277b15c5d08
497f5e4a-0c76-441a-b72e-724d7092d07e.ovf
info.json

In the ovf file there is no Nic section...

I uploaded the ovf on the same share as the logs

Hi, I upgraded an oVirt installation a month ago to the latest 3.6.7. Before
it was 3.6.0 if I remember correctly.
Everything went fine so far for a month or so.

A couple of days ago the the default gateway got rebooted and the physical
server hosting the HE decided to shut down the vm because it could not ping
the gateway.
The other host restarted the hevm but it now has *no nic*.
As a workaround I attached a virtio nic via virsh but every time the vm gets
restarted the nic get lost

After a bit of troubleshooting and digging this is what I found:

This is the /var/run/ovirt-hosted-engine-ha/vm.conf which, as far as I
understand, gets extracted from the HE storage domain

As you can see there is no nic, and there is no nic in the qemu-kvm

I extracted the vm.conf from the storage domain and the nic is there:

The local vm.conf gets continuosly overwritten but for some reason the nic
line gets lost in the process.

Can you please check/share /var/log/ovirt-hosted-engine-ha/agent.log?
Preferably all of it (including backups)? Thanks.
