Hello I am doing a research project (http://www.ites-project.org/) and want to be able to mount VM images (all kinds of VMs, starting with VirtualBox). For that libguestfs seems perfect. I am already able to mount the base HD, but I was not able to additionally mount the overlaying Snapshot files. Is there a way to mount several HD files onto each other ?

Mainly, I suspect, because qemu generally encourages you to use qcow2 external snapshots. This would have to be added to qemu, and then libguestfs would be able to support it almost for free.> Is there a way to mount several HD files onto each other ?Not sure what this means.
