Hi,

I'm not really sure what networking model I want in OpenStack terminology, but I'm very sure how I'd like my network to be setup. (Or rather, how I'm required to set it up.)

• No private IP's and no NAT.
• I need VLAN support, but not for all users/tenants (customers).

Most customers will reside on a "default VLAN" where we'd either like to have our own DHCP server, or if OpenStack software can assign the IP's automatically to the instances. However, no NAT, no private IP's, I have public IP ranges to use for this.

A tenant/user shall optionally be able to have 1 or more custom VLAN's (but still be able to have interfaces on the default VLAN). On these custom VLAN's a tenant/user is self responsible for DHCP, otherwise it should be manually assigned static IP's.

Is a setup like this possible with OpenStack? If yes, how? If no, what do you suggest instead?

In either case, is there some detailed documentation of all possible network configurations with OpenStack listed at the same place?

Edit: I have understood that I must install and configure openvswitch and quantum. Done that according to documentation and can't get that to work either. No matter what I do I just get: "Invalid input for operation: Unknown provider:physical_network default." when I try to create my default network with quantum. Any help from anyone?
