noVNC is used as a proxy and you have to use tokens to be able to connect
to different vms. For example, this how it's done in Sunstone.

When the vnc icon is clicked a new token is generated in the server:
https://github.com/OpenNebula/one/blob/master/src/sunstone/OpenNebulaVNC.rb#L146

then that token is used to connect to the noVNC proxy:
https://github.com/OpenNebula/one/blob/master/src/sunstone/public/js/plugins/vms-tab.js#L3195

Hope this helps.
