Sorry for the repost, I don't know if the previous message got to the
list...
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.
