Looking at block TODOs I saw qcow2 resize with snapshot. However I
would ask if this is technical possible with current format. The
reason is that snapshots have no size (only l1_size, QCowHeader have a
size field) however I think that size if part of machine state and is
not possible to compute exact size from l1_size.
Should this resize be posted to qcow3 update?
