You've already set it up, it's configured automatically :D The current AP holding the Virtual Controller is denoted by the * , so in this case it is Server Room AP. If you unplug this, the Virtual Controller IP will fail over to Conference Room.
Just a note, you want to set the Virtual Controller IP to in the same subnet as the AP's just not the same IP as an AP.
ACMA, ACMP, ACSA
