gstfsd, the root service on each compute that rewrites a shut-off VM's /etc/shadow and authorized_keys, did what any client on its port asked. Now it needs GSTFSD_KEY (64 hexadecimal characters, in the unit's /etc/default/webvirt-gstfsd) and does not start without it. Each connection gets a new challenge; the panel signs its request for it with HMAC-SHA256 and gstfsd checks the signature before any change, so a request recorded on one connection is refused on another. gstfsd signs its reply for the same challenge and the panel's nonce, and the panel accepts only that reply. Each compute has a gstfsd key, the host's GSTFSD_KEY: the compute forms and the API take it and never show it, and an empty value on an edit keeps it. The bootstrap script makes the key file once, readable by root only; the README shows how to make it and where the panel takes it. The traffic is still not encrypted: a remote panel's port stays open to the panel's address only.
