Make OS X login with two users, one in the background

I have an OS X server that also runs my living room TV, it is running Yosemite. I'd like to have it boot up loading the "TV" user automatically so the TV is ready to use but also load a "Server" user in the background so all of the necessary services start.

You can make the Mac do this if you auto-login as TV and then screenshare into it as Server that way two users are loaded on the box at the same time.

How can I do this without screensharing?

 

That is good to know about OS X Server; it is my first time running it.

The other things this box does:

- runs an Ubuntu VM serving a wordpress blog to public www
- serves as iTunes Media Server and phone sync'er
- runs a Minecraft server
- runs Transmission and NZBVortex
- runs Plex Media Server and VLC streamer

So with all those things I often want to login to the box with those processes and administer something or change something with iTunes, import music, etc, without disrupting the person watching TV. So optimally the TV user is what would start and be visible while the Server user would be on in the background and I could screenshare to it.
