Open Stack

Hi All,

I successfully tested the first patch:
    https://review.openstack.org/#/c/15022/
and would be really good to have it approved!

I think the second one:
    https://review.openstack.org/#/c/15023
is not required. I think having one agent responsible for two
openvswitch instances is not good, and that change is too specific for
the All-in-one deployment scenario, which is mainly used for dev/test.

My idea, is to slightly modify devstack instead, to end up with:
- Have one agent for both the dom0 and the domU openvswitch instances.
  Both running in domU, using different root wrappers, and different
  configurations (requires #15022 patch).
- Create another XenServer network - a new ovs bridge - and use that for
  connecting VMs, do not add any domU interfaces to that bridge.
- Use domU's eth1's network as a "physical" network. In domU, create a
  bridge, connect the eth1 to that bridge. Name this bridge br-eth1.
  Specify br-eth1 in bridge_mappings for the domU agent. In dom0's agent
  config, specify bridge_mappings to point to the bridge of the network
  where domU's eth1 is plugged in. Call this network physnet1.

I did some drawing here:

I am not a quantum expert, so let me know your ideas.

And If anyone has some core-spare time, could you please core-review
https://review.openstack.org/#/c/15022/ so that we could start using Quantum
with XenServer/XCP?
