Geoff, Kinda sort of what I am looking for but can you help me understand this statement taken from http://incubator.apache.org/cloudstack/docs/en-US/Apache_CloudStack/4.0.0-incubating/html/Installation_Guide/configure-vpc.html#add-gateway-vpc ?
"A private gateway can be added by the root admin only. The VPC private network has 1:1 relationship with the NIC of the physical network. No gateways with duplicated VLAN and IP are allowed in the same data center.? Given a multi-tenant environment does this actually imply that this network must be bound to a physical interface? Or does this mean that there must be a physical interface dedicated to this type of traffic which can then be carved up among multiple tenants based on the providers model? Jeffrey S.
