Your browser is denying the request because it violates cross-origin
policy. If you need to do this, you will need to either ensure that the
requests are not cross-origin, or use a proxy to insert the necessary CORS
headers (and enable CORS on your XMLHttpRequest instance) for the request
to succeed.

Before you go too deeply into this, though, it'd be nice to know what
you're actually planning to accomplish here. I'm not convinced this is a
good approach for ... just about anything. If you're just trying to provide
remote desktop functionality within your application powered by Guacamole,
there is an API for that (guacamole-common and guacamole-common-js) and
there is no need to embed the entire mainline web application, deal with
the REST API, etc.
