Hi,
I had this working just fine on one machine. Then upgraded to a
similar machine with more memory. Now it fails. I am trying to
read files from inside a successfully setup Linux Mint 22.1
Cinnamon QEMU VM for FreeDos.

Today (latest version) I installed the
libguestfs for "Debian/Ubuntu" without error:
sudo apt-get install libguestfs-tools
Here is the command I used to capture the files from inside the
VM image:
roe@d2:/media/roe/kem/gho/fDos$ guestmount
-a fDos14.img -m /dev/sda1 oBox
libguestfs: error: /usr/bin/supermin exited with error status 1.
To see full error messages you may need to enable debugging.
Do:
export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1
and run the command again. For further information, read:
http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs
You can also run 'libguestfs-test-tool' and post the *complete*
output
into a bug report or message to the libguestfs mailing list.
Here is the command again with trace:
roe@d2:/media/roe/kem/gho/fDos$ export
LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1
roe@d2:/media/roe/kem/gho/fDos$ guestmount
-a fDos14.img -m /dev/sda1 oBox
