comments needed for ip configuration

[Chris Ricker]

The crosstalk_ip and internal_ip variables need some explanation in the site.pp in this part of the config file:

# Change control_server to the host name of your control node
node control-server inherits os_base { class { control: crosstalk_ip => '192.168.242.10
'} }

# Change compute_server01 to the host name of your first compute node
node compute-server01 inherits os_base { class { compute: internal_ip => '192.168.242.2
1', crosstalk_ip => '192.168.242.21'} }

### Repeat as needed ###
# Copy the compute_server01 line above and paste a copy here for each additional OpenSt
ack node in
# your cluster. Be sure to replace the compute_server01 parameter with the correct host
 name for
# each additional node
