Re: [libvirt] Silently ignored virDomainRestore failures

What I'm tempted to do is add a command which sends a sigil to stderr to the end of the exec: migration lines specified by libvirt, and wait for either that sigil or an error to show up in the log for that domain before issuing the cont; if my memory is at all correct, libvirt should have some helper functions useful for that purpose already available.

Ugh, bad idea -- I was thinking only of the migrate-from-file case, and not of migration from any alternate source; any non-exec source doesn't allow for this hack.

Anthony suggested dropping -S from the command line on incoming migrations, and using "info status" to poll for when the guest resumes itself; however, this doesn't work for cases when the VM was saved or migrated in a paused state and the end-user expectation is for it to remain paused.

I'm tempted to add additional output to "info migrate" indicating whether an inbound migration is ongoing; however, this wouldn't help versions of qemu without the patch applied.
