Add property "quote-generation-socket" to tdx-guest, whihc is a property of type SocketAddress to specify Quote Generation Service(QGS). On request, connect to the QGS, read request buffer from shared guest memory, send the request buffer to the server and store the response into shared guest memory and notify TD guest by interrupt. command line example: qemu-system-x86_64 \ -object '{"qom-type":"tdx-guest","id":"tdx0","quote-generation-socket":{"type": "vsock", "cid":"2","port":"1234"}}' \Here you're illustrating a VSOCK address. IIUC, both the 'qgs' daemon and QEMU will be running in the host. Why would they need to be using VSOCK, as opposed to a regular UNIX socket connection ?
We use vsock here because the QGS server we used for testing exposes the vsock socket.
I will add more examples in next version to show that any socket type is supported.
