Open Stack

I'm running Mirantis OS 9.2 and using VLANs so you should be able to as 
well without using OS11.  It should provide you the option to use VLAN 
segmentation for networking while running the cloud environment creation 
wizard.  Once you create the cloud environment, you can't change this 
option, you must re-create the cloud to do so(as far as I'm aware of).
