Libguestfs - Mar 2023 - Changes in qcow2 not reflecting/visible

1.  What are you trying to do?

I'm trying to mount qcow2 using guestfish -remote, modify the qcow2 and
reuse the modified qcow2.



  1.  What exact command(s) did you run?
I have attached code.txt


  1.  What was the precise error or output of these commands?
While remounting the qcow2 I'm not able to see the modifications I have made
to the qcow2 during initial mounting. May I know why.


  1.  Enable debugging, run the commands again, and capture the complete output.
Do not edit the output.

export LIBGUESTFS_DEBUG=1

export LIBGUESTFS_TRACE=1

I have attached the debuglog.txt



Please let me know if you need more information...
Awaiting for a response.

Your script uses the "add-ro" command.

readonly

    If true then the image is treated as read-only. Writes are still allowed,
    but they are stored in a temporary snapshot overlay which is discarded at
    the end. The disk that you add is not modified.
