The xterm console never connected: socketiod expected a different token format, its worker had no compute credentials, one global console was shared by every client and its output broadcast to all of them, and the Docker image did not run socketiod at all. - console/tokens.py: one authorize() for noVNC and socketiod; the signed token is the only credential, checked at connect time. - socketiod: one pty worker per client (consolecallback with the instance id), one session per VM, a session cap, input and resize checked; the parent never opens libvirt. The engine.io same-origin check is on. - consolecallback: opens the console with the compute's credentials and exits with a message when it cannot. - Docker runs socketiod as a runit service; nginx proxies /socket.io/ with Host and the scheme for the origin check. Supervisor and systemd start it as well; WEBVIRTCLOUD_SERIAL_CONSOLE=1 enables it. - Tests: token and session unit tests, socketiod as a process, and a live test that reads SeaBIOS from a wvc-test VM on the TCP and SSH hosts.
