Thanks for all your help guys. I am on 4.0 currently. I will go the agent route and see what I can do.
As for putting in the feature request. I will do that as well since I am sure the more people use cloudstack the more people will run into this. I really thing the UI is far superior experience. On a side note, the VLAN stuff needs some better documentation around configuration with KVM. Is there a place I can add some of my notes once I get past this disk issue and test everything?
