Need more doc for libvirt-console-proxy

Hello, I'm making a web app for my company that will enable different teams to manage their own VMs. I wish to make possible to interact with each VM console, so I plan to use some xterm.js with websockets. So I discovered libvirt-console-proxy [1] when I looked for something to put a libvirt console into a websocket. That seems like the right tool for the job. The only doc I found is this article from 2017 [2]. After trying to understand from this article and from --help, I still have many questions. I am really bad at reading code so I can't even get answers from the sources. My main concern is: How a client is supposed to talk to the proxy? It is said that a security token must be provided. How? HTTP header? Which header? Am I missing something in websocket protocol? I think an example client implementation would help a lot. Also, I tried to use virtconsoleresolveradm to set up metadata on my domains like explained in the article [1] : ./virtconsoleresolveradm enable milou Enabled access to domain 'milou' But that doesn't seem to do anything (except defining the metadata namespace in the XML): virsh metadata milou http://libvirt.org/schemas/console-proxy/1.0 <consoles/> I precise that I have already this in my XML: <serial type='pty'> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> </serial> <console type='pty'> <target type='serial' port='0'/> </console> Should I remove that? Should I edit that? Thanks for your help. Guy Godfroy [1] https://gitlab.com/libvirt/libvirt-console-proxy [2] https://www.berrange.com/posts/2017/01/26/announce-new-libvirt-console-pr...
