The installer cannot use the network for that? Maybe it would be
acceptable to not add such a property, and document that libosinfo users
should remove the iso from the libvirt XML only after the last reboot?
This would mean the installation ISO would always be visible in the
guest OS until the first user-initiated reboot, but maybe that's ok?
We could also add some ejection of the ISO to the post-install scripts,
but that's getting complex and ugly ;)
Not really saying your approach is bad, on the contrary, just thinking
out loud ;)
