This it?

Seems like that would work. Might need to do it as root in case the
kernel doesn't allow an ordinary user to use up all the free space on
a disk. And don't forget "rm /sometempfile" once the dd finishes
with out of space errors.
Of course you could take a completely different tack and use
qemu-img convert to change the qcow2 format file to a raw
disk image and modify the virtual machine to use that new file.
I qemu-img to a raw and then back to a qcows2.
Dump/resore still did not restore right.
Now I converted to a raw and am about to see
if dump/restore will restore back correct.
If that does not work, I am going to dd /dev/zero
dump/restore restored a "raw" file perfectly.
Interesting. sha256sum came back different for
before and after (.000 is before)
