Instead of this, use:
let g = open_guestfs ~identifier:"template" () in
‘open_guestfs’ is a wrapper around ‘new guestfs’ defined in
common/mltools/tools_utils.ml which applies the --trace and --verbose
flags from the command line and lets you set a per-handle identifier
for debugging. You can choose any useful identifier for the handle,
in case "template" is not a good one.

Is this the right thing to do? qemu-img info returns the compressed
size in this case, which is ... wrong (maybe?)?
If a compressed image is wrong here then you could use
detect_file_type from common/mltools/tools_utils.ml to detect that
situation.
