This is a bug. libvirt should save a copy of the original configuration
at the time the guest starts, so any live changes only remain for the
duration of that boot and automatically revert at shutdown.

As a datapoint, VirtualBox has an option (per guest) to either keep or
not keep the changes made while it's running.  It's a persistent setting,
and can be toggled while the guest is operating, so the user is able
change whether they keep changes or not.

Having our approach hard coded to never keep changes sounds a bit
non-optimal, if there are use cases where people might like to keep them.

Though, I haven't read the full thread for this... ;>
yeah, agree, actually, currently we don't allow to make changes on the
persistent configs.
