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 Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing net user: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing network: ovirtmgmt/1da8c5b7-999c-4ada-8287-1f35de6ce21d Oct 22 16:33:31 office-wx-otest vdsm[2634]: WARN Attempting to remove a non existing net user: 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.
