Re: [libvirt] [PATCH v7] qemu: Introduce state_lock_timeout to qemu.conf

When doing some job holding state lock for a long time, we may come across error: "Timed out during operation: cannot acquire state change lock" Well, sometimes it's not a problem and users want to continue to wait, and this patch allow users decide how long time they can wait the state lock.
