I have produced what I think are two patches that will fix this. I have compiled them but I haven't tested them. Konrad, are you able to check whether they fix your bug ?
I too saw this bug just before Konrad's report, but the patches don't seem to help. Running a script that continually saves and restores domains will eventually lock libvirtd with essentially the same traces reported by Konrad
I'm a total idiot. I do the recheck but I don't pay any attention to the result.
Your second patch was updating revents which was used in the next if, what have I missed?
I will send an updated approach which does this centrally.
Ack, that's probably best anyhow.
