I'm not convinced that the steps there are 100% correct. We do call
virDomainObjSave() after live attach:
https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_driver.c#L...
The two steps for hot-unplug in the BZ actually failed.
(sorry I didn't mention
the result in the steps)

Yep. For a few cases it is hidden in BeginJob() and EndJob() but not for
agent jobs.
