libvirt: Generic Framework for Securing VNC and SPICE Proxy-To-Compute-Node Connections

Registered by Solly Ross on 2014-04-09

Currently, while the noVNC and HTML5 SPICE clients can use TLS-encrypted
WebSockets to communicate with Websockify (and authenticate with Nova console
tokens), the encryption and authentication ends there. There are neither
encryption nor authentication between Websockify and the hypervisors'
VNC and SPICE servers.

This blueprint would propose introducing a generic framework for supporting
MITM security for Websockify to use between itself and the compute nodes.
