I confirm that using "-c" option the size of the converted image is the
same as the 0.10 version. Thanks.
I didn't find a way to verify in advance if an image is compressed or
not.. is there?
No. Qcow2 file is not actualy compressed, it includes compressed clusters.
This can be detected by looking at qcow2 metadata, but it is not exposed by
qemu-img.

I confirm that after updating the engine (not yet the hosts) from 4.2.6.4
to 4.2.7.5 fixes the problem, both for the displayed disk size inside the
gui bar during upload (1.5Gb and not 66Gb) and for the successful
completion.
Yes, this is engine bug so upgrading engine is enough.
But you should update the hosts to get other fixes and improvements like
