For ssh key auth, it would be helpful if both the raw key file contents and the passphrase could be stored as libvirt secrets. Is that possible? If so, qemu can pass both to libssh2_userauth_publickey. Almost as in this example: http://libssh2.org/examples/ssh2.html , combined with looking at how libssh2_userauth_publickey_fromfile is implemented: http://git.libssh2.org/?p=libssh2.git;a=blob;f=src/userauth.c;h=a0733d5da... I'm also a bit concerned that the solution should be usable for ordinary users. qemu -drive file=ssh://... currently Just Works. ---- Next questions: - How should host_key_check be modelled via the libvirt XML / API? - We want the user to be able to select different authentication methods (at least, password, publickey, agent [insecurely]). How would you see these being modelled in the API? Particularly since these may require associated secret(s).
