Open Stack

Hi All

When I setting neutron for openstack network, I got some problem and
doesn't know why.

I reference"Neutron Networking with Open vSwitch and Provider Networks
<http://docs.openstack.org/developer/devstack/guides/neutron.html#disabling-next-generation-firewall-tools>"
to setting my openstack network.

Control node is work fine and NIC eth0 IP address can assign to br-ex
successful
Compute node NIC eth0 assign to br-ex failed ,and Compute all API service
can't connect to Control

My compute node local.conf  in below

The question are
1.In Open vSwitch provider networking options
PHYSICAL_NETWORK=default  <-- Is mean it use my NIC or  my public network ?

2.PUBLIC_INTERFACE is same with FLAT_INTERFACE?

3.Why the SERVICE_HOST connect failed?
I can ping or connect to SERVICE_HOST via other server,but compute node
can't.

4.My compute node br-ex doesn't be assign eth0's IP,so it can't go out ? If
yes,how to fix it ?


Best Regards,
