It seemed rather clear from the report, but I wanted to try myself.
First I tried with a bind mount as shown above as that would make the setup
even simpler (doesn't need an extra disk).
But I found that this works.

[ OK ] Stopped target Local File Systems.
And the shutdown took quite a few seconds, so on shutdown the ordering was not
an issue.
Note: Even worked after I changed it to use an extra disk.
This is due to:
libvirt-guests.service
After=libvirtd.service
which again is:
After=local-fs.target
So this actually works fine on shutdown and restart for me.
Ordering seems correct.
I retried it a few times but it worked every time - the ordering was
strict.
@Erlend - could you show the journal content of e.g. the failing
shutdown&startup.
It really should always be:
boot: local-fs.target -> libvirtd.service -> libvirt-guests.service
=> the FS should be up when needed.
shutdown: libvirt-guests.service -> libvirtd.service -> local-fs.target
=> the FS should go down after no more being needed
** Changed in: libvirt (Ubuntu)
Status: New => Incomplete
