Hi,
I'm trying to clean up old bugs right now.
On this particular case there never was an actionable level of debug/info or a chance to recreate.
Furthermore I have not seen "similar" issues come in since then so we really would need to understand better what config/setup made this trigger the issue.

I say "similar" in quotes as the error message unfortunately is pretty generic and could mean a lot of various things. But so far all of them ended up either unreproducible
https://bugzilla.redhat.com/show_bug.cgi?id=1918211
https://bugzilla.redhat.com/show_bug.cgi?id=1821277
or misconfigurations in other layers of the virt stack which were not mentioned to be present here
https://bugzilla.redhat.com/show_bug.cgi?id=1474584

Therefore since this does not seem actionable without more insight into what triggers the issue I ahve to mark the case incomplete :-/
