It's possible to hit the following situation during qemu p2p live migration: 1. qemu has live migrated and exited (making virDomainObjIsActive() return false) 2. the live migration job is still in progress, waiting for a confirmation from the remote libvirt daemon. This may last for a while with a presence of networking issues (up to keepalive timeout).
There's probably more which could happen, or there will be and the message will never be perfect. On the other hand it does not hurt to make it a bit more nicer for someone with just a few lines. Reviewed-by: Martin Kletzander <mkletzan@xxxxxxxxxx>
Any attempt to start the domain again would fail with "domain is already
being started" message which is misleading in this situation as it
doesn't reflect what's really happening.
Add a check for the migration job and report a different error message
if the migration job is still running.
