Short answer: currently there is no support for that in StarCluster.

Longer answer: While the boto (AWS Python) run_instances() API does
offer support for assigning specific private IP address (by using
parameter "private_ip_address") in a VPC subnet, there is a limitation
of starting only 1 instance when private_ip_address is specified.

Thus, if you want to do it that way, the StarCluster code will need to
pass in the "private_ip_address" parameter when starting the master
node. Then the slave nodes will need to be started in another
run_instances() call. It should be doable (with some code changes) as
just running a 1-node cluster, then adding new nodes is my recommended
way of starting large clusters in EC2.
