Add more detailed examples for provider networks in quantum

[Jasper Aikema]

At this moment, I miss some detailed examples of when to do what.

In the docs it is clear how to do things. But not what you have to do, to create a working scenario.

For example: I want to create a provider network, with floating Ip's, and have two NIC's. I wasn't able to do this with the current documentation.

The connection of quantum to nova was working. But i wasn't able to make sense if i needed a router, how many networks and subnets (with the quantum command), and what to do with the bridges, interfaces and ports (with the ovs-vsctl command).

I think it will be a good idea to document what you ave to do, and why. Maybe also more about debugging the problems.

In the following quantum command,

quantum net-create --tenant-id $TENANT_ID net1 --provider:network_type vlan --provider:physical_network physnet1 --provider:segmentation_id 1024

provider:segmentation_id is actually a VLAN id which is used in the network for controller and compute nodes. This same VLAN id is also passed to the physical switch that interconnects controller and compute nodes. Try to avoid use VLAN id 1 since some physical switches do not forward VLAN 1 frames by default.

Thanks.

I want to know if the Demo Setup is either incorrect or not meeting this need?

(I also wonder if people don't know to click NEXT> links?)

Feedback on the Demo Setup above:
"I'm myself in the middle of that, the guide def. needs more explanations - especially about the network topology. I've been able to make the private network routing work by following that guide, but indeed, still stuck with the floating ips routing."

Will a bug fix for 1064643 also fix this bug?
