*Ref:* www.libguestfs.org/guestfs-faq.1.html#debugging-libguestfs 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. - *Mark Kleiman*, www.KleimanUp.com Engineer Teacher 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
