I kept reading and reading to find where you say you unmounted in on the host,
and then... :)

Subvolumes are very much like directories, not any kind of subpartitions.

Imagine you'd try to use the same ext4 from the host and from a VM guest,
saying "but they both store their data in separate folders!"
