[Bug 1025244] Re: qcow2 image increasing disk size above the virtual limit

[Serge Hallyn]

I don't know of any qcow2-based workaround.

Is anyone actively working on fixing the qcow2 code?  In particular, the
fact that after removing snapshots, un-used blocks are not reclaimed and
disk size is never reduced?

One possible workaround (the one I would use) would be to use lvm-based
snapshotting instead.
