guestfish -a IMAGE.qcow2 -i guestfish: no operating system was found on this disk If using guestfish ‘-i’ option, remove this option and instead use the commands ‘run’ followed by ‘list-filesystems’. You can then mount filesystems you want by hand using the ‘mount’ or ‘mount-ro’ command. If using guestmount ‘-i’, remove this option and choose the filesystem(s) you want to see by manually adding ‘-m’ option(s). Use ‘virt-filesystems’ to see what filesystems are available. If using other virt tools, this disk image won’t work with these tools. Use the guestfish equivalent commands (see the virt tool manual page).
