Comment 3 for bug 1816727

AFAICT, this is behavior in websockify and I'm not yet sure whether we can avoid it.

This is our code for creating the websockify.WebSocketProxy:

https://github.com/openstack/nova/blob/be8af28a4ff111f99da9b34ee36a90a8a25d5bef/nova/cmd/baseproxy.py#L68-L80

where we pass the RequestHandlerClass=websocketproxy.NovaProxyRequestHandler to websockify.WebSocketProxy. Then, in websockify.WebsockifyServer.do_handshake, it will create an instance of the RequestHandlerClass:

https://github.com/novnc/websockify/blob/6e09ec25486f431e2acc463f994c4eb4bebc6ddd/websockify/websockifyserver.py#L538-L622

which is our websocketproxy.NovaProxyRequestHandler. The arguments to the class are the socket object and the address. Is there some way we can tell from the socket object that the message is a TCP RST? If so, maybe we could avoid creating a new ComputeAPI object in that case.

Otherwise, I'm not sure how we could do anything about this in nova vs websockify.
