1:38 a.m.
When I start VM instance, the VM can't get IP address. Could someone help me on this
?
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
- 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.

Port br-int
Interface br-int

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.
Thank you!
