That is, migration status first changes to "failed" just to change to
the correct "cancelled" state in a few moments later. However, this is
enough to let libvirt report migration failed for unknown reason instead
of having been cancelled by a user.
This should really be fixed in QEMU but I'm not sure how easy it is.
Is qemu going to fix it? I'd rather see it done that way rather than
fixing it up in libvirt.
