Deploy additional FA for VMware

I initially deployed the VMware App with a single FA virtual appliance. What does it take to add additional virtual appliances? What config files need to be changed?

Question 2) How can we "pin" a virtaul appliance to a VMware cluster? We have many clusters and would like to have at least one Splunk Virtaul Appliance deployed per cluster. What configuration files need to be changed?

thanks,
