Following the arguments made before on this bug about this being an
uncommon or maybe even unsupported setup variant I'm marking the tasks
that represent backports as won't fix.
This setup only becomes more reasonable after [1] which isn't on
anyone's active work-queue atm AFAIK - and even then
There still are known issues around volume usage with apparmor isolation which
are tracked elsewhere. But you are right - thanks Garry - one of the inderlying
issues about
a) modifying non-local storage

This appears to have already been fixed for some cases. I was able to
snapshot a qcow2 volume on 21.04 (libvirt 7.0.0).

disk type of file, and snapshots work [mostly - see my next comment].
i'd never used/tried snapshots with this particular configuration. i'm

i can now create snapshots if using --disk-only, but i guess this is an
"external" snapshot? which leads to other problems, like not being able
to delete it:

I looked a bit more into this and more and more get the impression that
this particular setup has not and is not supported.
