Description
Based on C12G Lab's "Using qcow Images" document, I've created patches for the tm_clone.sh files to take advantage of qemu-img for creating copy-on-write disk images. Also included in the patches is a flag, set to false by default, that indicates whether to use the qemu feature. Therefore, the C12G document can be updated to instruct users to change the flag if they so desire.
I would still like to get similar changes incorporated into "tm_mkimage.sh" as part of this feature ticket.

I'm attaching updated diffs for the two tm_clone files.
These scripts are known to work in basing a Copy-On-Write disk within my environment.
