Hi, I am using Openstack Mitaka release. My setup consists of One Openstack Controller and One Openstack Compute Node. My compute node is configured with OVS-DPDK. I am using openvswitch driver and installed Neutron Openvswitch agent on the Compute Node. I am able to launch a VM on the Compute. But, not able to get IP address to the VM. When I search the logs, I found errors in Neutron OpenVswitch Agent (/var/log/neutron/neutron-openvswitch-agent.log) logs. The following pastebin path describes the error:

Can anyone give me some clue about the error?

Regards, Srikanth.

you can't use 'normal' firewall driver (iptables hybrid driver) when you use DPDK acceleration You need to use neutron.agent.firewall.NoopFirewallDriver, so configure Neutron accordingly.

The firewall driver you can consider is 'native OVS' one,

Hi, Now I am able to get IP address to the VM. And,I assigned a floating IP to the VM. But, not able to ping floating IP from external. And also,sometimes I need to restart Neutron-Openvswitch-agent in Controller and Compute to get IP address. What could be the issue? Thanks for your help.

Hi Srikanth

How are you installing Openstack with DPDK?
