While new versions of qcow2 have some extensions that let the
last-written sector be tracked for use on device-backed partitions, the
expectation is that you'll (really) just use the raw partition; qcow2
more than takes back the performance gain from getting your host
filesystem out of the loop.

Right -- folks doing this route go raw rather than qcow, so it's just a
matter of resizing the partitions / filesystems within the guest.
