HI,
As you've known, vhd-util and qemu-img both provide the capacity for
resizing the original disk, but why is virt-resize designed to involve
two disks, not only original disk? Is there any concern? Is it
possible that only one original disk is involved in virt-resize?

I'm guessing this question is why virt-resize doesn't work on disk
images in-place.
This I hope is answered in the FAQ here:
