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
