Hi! I also got hit by the same warning on the logs that completelly misleaded me (thinking it was the error stopping me). I wanted to comment just in case some other people may also get hit by it.
After upgrading a cluster from buster to bullseye I couldn't bring the guests back to my upgraded nodes. Ganeti would refuse to move them because there was a problem, when I looked at the ganeti logs I could only see the message: ganeti.errors.OpExecError: Could not pre-migrate instance sid: Failed to accept instance: Failed to start instance sid: exited with exit code 1 (kvm: -usbdevice tablet: '-usbdevice' is deprecated, please use '-device usb-...' instead This was completely misleading, as this message is only a warning, not an error, the real error was... kvm: -vnc 127.0.0.1:5142: keymap include files are not supported any more Which I just couldn't see anywhere until I looked at the kvm logs, don't know why I didn't see it, now I see it was on Ganeti's logs as well. Anyway, the error was caused by me having the keymap set to spanish, so what I did was: gnt-instance modify -H keymap= guest for every guest, but having them change the keymap meant a reboot off all guests. Having done that I thought I had finished, as I had all the nodes updated to bullseye and cleaned, the cluster is running ok and everything looks fine, however I got hit by another bug (#993920).
