4:35 p.m.
Hello all,
I just upgraded one of my test oVirt setups to latest.
Post reboot, the machine lost network and hosted engine didn't start.
When I connected to the machine, I noticed all the
/etc/sysconfig/network-scripts/ifcfg-* files disappeared. No idea why /
how. (Possibly I did something wrong and forgot about it.)
Long story story short, I copied the two missing files (ifcfg-onb0 ethernet
device configuration and the ifcfg-ovirtmgmt bridge configuration) from
another ovirt host, changed the ovirtmgmt IP address and UUID to match the
UUID reported in logs as missing and restarted NetworkManager and restarted
all the oVirt related services (vdsmd, supervdsmd, ovirt-*, etc).
Sadly enough, even with both onb0 and ovirtmgmt up, vdsm still complains
about the missing network (ovirtmgmt) and refuses to start the hosted
engine.
Reboot doesn't seem to change anything.
In the main log I see the following errors:
Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non
existing network: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d

As it is one of my oVirt test setup, I can simply redeploy the host and
continue from there, but I rather use this experience to learn how to fix
oVirt such issues in the future.
Logs attached.
