Just do: guestfish -i systmp-img.img --ro To extract the data, I suggest you use the guestfish tgz-out command (see the guestfish(1) man page). If you want to actually mount the partition(s) as filesystems on the host, you need to use another command, guestmount. This uses FUSE and will let you mount the filesystem(s) on a local directory, root permissions also not needed. Eventually we'll modify virt-manager so you can double click on an image and it'll appear mounted, but in the meantime you'll need to read the manual page guestmount(1). > I suspect it's because the processor isn't kvm-capable, but it allowed > me to install and upgrade all the necessary packages... You don't need KVM, although libguestfs is a lot faster if KVM is available.
