The easiest configuration (from Packstack's point of view) would be to use two
different physical networks, with one NIC connected to each. So, for example,
you could have eth0 of all nodes connected to the management network, and eth1
connected to the VM / data network.

Otherwise, you'd use two VLAN devices over your single NIC
(You'd have to configure this, Packstack doesn't do this for you).
Then place eth0.100, eth0.200 in your answer file where appropriate.

If you get any failures, you could post your answer file and I'll take a look.
