Hello Andreas,
I'm tested the qcow2 drivers again with saveas a they do work for me. Could
you attach more logs in order to debug this?
/var/lib/one/config (be sure to blank the passwords if any)
/var/log/one/<vmid>.log
and onedastatore show, and oneimage show of the image and its datastore.
Regards,
Jaime
