hi,

As a part of the test suite for xen that I've started off - I needed a way to inject a ssh key into the image [1]; so have come up with this : https://github.com/CentOS/sig-virt-t_xen/blob/master/scripts/inject_ssh.sh ; its not pretty and it wont handle lots of use cases, but it does what is needed at hand.

Comments ?

I would have first looked at libguestfs suite, virt-edit maybe. It has tools specifically designed to interact with VM filesystems.

libguestfs just uses libvirt or QEMU under the hood, depending on the version of the library. I think that spawning QEMU directly is simpler.
