It looks OK, except that guestfish is printing a UTF-8 progress bar
which your terminal doesn't understand.  guestfish uses the following
test to decide whether or not it can output a UTF-8 progress bar:

    bar->utf8_mode = STREQ (nl_langinfo (CODESET), "UTF-8");

You can use 'guestfish --no-progress-bars' to disable progress bars.

The code looks OK.

It seems you might be using a vhd-format disk image.  It seems most
likely that qemu is having some problems decoding this format.

After adding the disk (in guestfish) and using 'run', do general
commands like 'list-filesystems' or 'list-partitions' work?

If you add '-v' option, does qemu give any error messages?

If you convert the image to raw format, does it then work?

Rich.
