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#L783... <https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_driver.c#L7834>
The two steps for hot-unplug in the BZ actually failed. (sorry I didn't mention the result in the steps)
In that case, we have another problem - the domain is marked as "tainted: use of host cdrom passthrough" even though the hotplug failed and qemu has never saw host cdrom. And the same goes for "tainted: network configuration using opaque shell scripts" - the taint happens before any hotplug is even attempted (and thus possibly even when the script did not even run).
