This bug report is unrelated to this patch series. In the future,
please start new email threads for unrelated discussions.

This output doesn't show anything unexpected. You converted a VHD file
to qcow2. The guest sees a 127 GB virtual disk for both the VHD and the
qcow2 file.
You didn't show the part where the VHD is 290 GB.
Can you post step-by-step instructions for reproducing the problem?
Thanks,
Stefan
