I agree with Ravi.

If your use case is that you just don't want to be nagged by the browser about your self-signed certificate, why not just import the CA into your browser?

I am not sure we can do what you are asking for. A lot of stuff is not going to work. AFAIK you will need a dedicated machine to run ovirt engine on the default ports.
