I need a way to provide information within the Guests while using KVM/Qemu and Libvirt.

Is there a way, for example, to have some kind of metadata accesible from within the Guest? For example, SSH public keys and stuff like this?

here's a use case:

  • You create a Guest.
  • You add a public SSH key into the metadata
  • You add a script that checks for this at boot time and stores writes it into /root/.ssh/authorized_keys

You can use libguestfs to fetch the required information directly from the VM after it has been installed.
