I tried that too, no lucky.
>From tcpdump ,it seems br-int does not forward any packet to interfaces connect to br-p3p1, which connects to physical network...

Hi, Gary
Yes, I'm aware of that packstack does not support quantum yet. The whole setup was installed manually.
I did run quantum-server-setup and quantum-host-setup, I tried linuxbridge plugin too, it has no issue for VM to get IP address, but openvswitch has issues on this...
ok.
if you configure and IP address manually on the VM are you able to ping the port of the DHCP agent?
you can get the IP from quantum port-list

Hi Kimi,
Thanks for the mail. Please see the inline comments below. Please note that at the moment we do not have packstack support for Quantum so there is a little manual plumbing that needs to be done (not sure if you have done this already).
On the host where the quantum service is running you need to run quantum-server-setup and on the compute nodes you need to run quantum-host-setup (please note that the relevant keystone credentials need to be set too).
Thanks
Gary

When I start VM instance, the VM can't get IP address. Could someone help me on this ?
I will try
3 nodes Setup with RHEL 6.4 OS + rdo grizzly repository.
* Controller node:
Services: Keystone+Glance+Cinder+Quantum server + Nova services
Network: bond0(10.68.125.11 for O&M)
* Network node:
Services: quantum-openvswitch-agent, quantum-l3-agent, quantum-dhcp-agent, quantum-metadata-agent
Network: bond0(10.68.125.15 for O&M) , p3p1 for VM internal network, p3p2 for external network
Please note that RHEL currently does not support namespaces so there are a number of limitations. We are addressing this at the moment. If namespaces are not used then it is suggested that one does not run the DHCP agent and the L3 agent on the same host. The reason for this is that there is no network isolation.
* Compute node:
Services: nove-compute and quantum-openvswitch-agent
Network: bond0(10.68.125.16 for O&M), p3p1 for VM internal network
* Switch setup tagging for vlan 1000-2999 for p3p1 ports(VM network) of network and compute nodes.

5. ovs-vsctl show on compute node:
8d6c2637-ff69-4a2d-a7db-e4f181273bc0

Interface "int-br-p3p1"
Port br-int
Interface br-int
type: internal
ovs_version: "1.9.0"
On compute node, I can see dhcp request packet from tcpdump on qvo56a4572c-dc, but it seems the packet is not forwarded out since I can't see packet from int-br-p3p1 on br-int or any port from br-p3p1.
Any chance to get the DHCP and the L3 agent configuration files? Please check that use_namespaces = False in both of these files.
Are there any log errors?
Thank you!
Regards,
Kimi
