qemu no-shutdown behavior in libvirt

[Luna Xu Yamada]

Hi Peter,

Sorry for the HTML format. I’m now sending from a different client not sure
it solves the problem... Thanks for replying and confirming the feature is
not there. I’ll be happy to help or contribute in anyway.

The reason I want to do this is I can continue my jobs for example backup
(drive-backup) after VM gets shutdown by the user, and I'm able to check
the status of the job through qmp commands. I'm moving to libvirt from qemu
to manage my VM, and I'm struggling with how to do the same thing through
virsh. I'm able to pass the -no-shutdown flag into qemu but it behaves
differently in virsh when I shutdown the VM. Much appreciated if someone
could give me a hint.</div>
