This is my instackenv.json for 1 compute and 1 control node to be deployed.
{
    "nodes": [
        {
            "pm_type":"pxe_ipmitool",
            "mac":[
                "08:9E:01:58:CC:A1"
            ],
            "cpu":"4",
            "memory":"8192",
            "disk":"10",
            "arch":"x86_64",
            "pm_user":"root",
            "pm_password":"calvin",
            "pm_addr":"192.168.0.18"
        },
        {
            "pm_type":"pxe_ipmitool",
            "mac":[
                "08:9E:01:58:D0:3D"
            ],
            "cpu":"4",

        }
    ]
}
