Public bug reported:
While attempting to use "virsh" commands this error occurs:
Oct 27 08:52:22 boron libvirtd: 08:52:23.000: 25851: error :
qemuDomainObjBeginJobWithDriver:453 : Timed out during operation: cannot
acquire state change lock
While the error state is present certain commands like "virsh shutdown"
and "virsh destroy" elicit that error message and fail to work
completely I found that if I kill the kvm guest processes
$ kill -9 $(ps ax | grep '/usr/bin/kvm.*guestname' | awk '{print $1}')
Then "virsh start guestname" would work.
I'm not certain that the number of VM guests is the issue, however, this
happens more frequently to me on systems with larger numbers of guests.
We have one with 14 guests and another with 53.
