Comment 4 for bug 1500688

@Ruoyu Zhang:

I don't see anything related to the REST API call for the action "get_vnc_console" [1]. This is the entrypoint which gets called by Horizon and the CLI. This call gets routed to the compute manager which will create a debug log "Getting vnc console" [2].

Please make a grep for the request you mentioned "req-6f260624-56ad-45fd-aa21-f86fb2c541d1" and for the uuid of the instance in the log files ("/opt/stack/logs").
