That does not matter. We keep state XML for all running domains, regardless if they are persistent or transient. But since the daemon does not restart, I suspect we have a bug somewhere. BTW: you can check if the state XML for domain still exists. We pass -name $domname to qemu, and the state XML should then be:
/var/run/libvirt/qemu/$domname.xml
Also, there is PID of the qemu process - can you check if they match?
Xml is absent, this is not strange, because libvirt log says, that domain is shutdown. So i think libvirt cleanup xml and pid files for this domains
Now i'm have the same issue. I'm do live migration on another node, qemu log says that domain receive 15 signal and shutdown. But as i see in process list: root 29561 0.1 0.2 1599628 743796 ?
