This is very helpful when we want to log and report why we could not acquire a state change lock. Reporting what job keeps it locked helps with understanding the issue. Moreover, after calling virDomainGetControlInfo, it's possible to tell whether libvirt is just stuck somewhere within the API (or it just forgot to cleanup the job) or whether libvirt is waiting for QEMU to reply. The error message will look like the following: # virsh resume cd error: Failed to resume domain cd error: Timed out during operation: cannot acquire state change lock (held by remoteDispatchDomainSuspend) https://bugzilla.redhat.com/show_bug.cgi?id=853839Signed-off-by: NJiri Denemark <jdenemar@redhat.com>
