The process for starting up a QEMU guest holds locks on various data structures. These same locks are needed when running a variety of other commands such as those run by virsh list. So those commands will be blocked until the guest startup lock is released, which in turns is pending on the hook script exiting. This why hook scripts should never call back into libvirt APIs, and why they should also try to be as fast as possible at execution.
