[libvirt] [BUG]libvirt doesn't show the real state of vm

Hi, I notice that monitor.sock still exist when I send SIGKILL to qemu process by accident, and I can't find the qemu process through `ps -ef |grep qemu` command. Then I execute `virsh list --all`, libvirt just show that the vm still in running state. I can't find log "Received EOF on xxx" either when set log level to debug. Any suggestion will be appreciated!
