This time, it appears the problem is more recent. I initially suspected commit d1c7b00b (Feb 2013, v1.0.3), since that rearranged the locks inside virDomainObjListRemove, but even after instrumenting that function, I was unable to get a crash; instead, I got the expected lookup failure: # virsh undefine fedora-local& sleep .1; virsh dominfo fedora-local [1] 25898 Domain fedora-local has been undefined error: failed to get domain 'fedora-local' error: Domain not found: no domain with matching name 'fedora-local' [1]+ Done virsh undefine fedora-local It's too late for me now to search any more tonight, but on the bright side, that narrows down the search, and we have at most two releases affected (rather than all the way back to 0.10.0 on the race that originally spawned this thread).
