Hi,

Can you see the dhcp port in port-list? If not, then you should check if the dhcp agent is properly running and connected.

Otherwise, how is your 'private' network mapped in configuration files? All the mappings should refer to some bridge which is then connected to a phys int.

If you could post your whole conf files as well as brctl output that would be helpful.

New question #231347 on quantum: https://answers.launchpad.net/quantum/+question/231347 (https://answers.launchpad.net/quantum...)

Hello,

I created two networks a public and a private network. Here's my conf:

CONTROLLER_HOST=172.25.193.119 PUBLIC_INTERFACE=eth0 PUBLIC_NETWORK=172.25.193.64/26 PUBLIC_GATEWAY=172.25.193.126 FLOATING_RANGE_START=172.25.193.108 FLOATING_RANGE_END=172.25.193.111 PUBLIC_IP=172.25.193.120 PRIVATE_INTERFACE=eth1 PRIVATE_VLAN_START=1100 PRIVATE_VLAN_END=1109 ZONE=lannion

quantum net-create priv1 --provider:physical_network private --provider:network_type vlan --provider:segmentation_id $PRIVATE_VLAN_START quantum subnet-create --name priv1_sub priv1 $PRIVATE_NETWORK

quantum router-create router1 quantum router-interface-add router1 priv1_sub quantum net-create ext --provider:network_type flat --provider:physical_network public --router:external True quantum subnet-create --name ext_sub ext $PUBLIC_NETWORK --allocation_pools type=dict list=true start=$FLOATING_RANGE_START,end=$FLOATING_RANGE_END --enable_dhcp False --gateway_ip $PUBLIC_GATEWAY check_error_code "Quantum: can't create external subnet" quantum router-gateway-set router1 ext

After creating all the components, the VM instances cannet get an IP from DHCP,

I have a network node, controller node and a compute node Any ideas

Thanks for helping me

hi, Suggest turn off firewall on all nodes first and then have a try. Stop service quantum-l3-agent if you use a RHEL OS and put quantum-l3-agent and quantum-dhcp-agent together, because RHEL has a limitation now, then restart quantum-dhcp-agent. Make sure dhcp interface->linux-bridge->ethernet works well both on network node and compute node. If not, show these detail information. The "pri" network you created is a typer of vlan, which needs the physical layer support the specified "segmentation_id" when you use multi-nodes.
