1. What are you trying to do? I’m trying to mount qcow2 using guestfish –remote, modify the qcow2 and reuse the modified qcow2. 2. What exact command(s) did you run? I have attached code.txt 3. 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. 4. 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.
