Openvswitch agent is not able to work

[leon153]

Hi, I met a quantum issue: After install any node, the quantum plugin openvswitch agent service would be working. (Commands “service quantum-plugin-openvswitch-agent status” and “quantum agent-liat” both show fine). However if I reboot the Ubuntu, then this service would be stopped, and couldn’t not enable anymore. Each time issue command “service quantum-plugin-openvswitch-agent start”, /var/log/quantum/openvswitch-agent.log would show: 2013-05-22 22:03:13 ERROR [quantum.plugins.openvswitch.agent.ovs_quantum_agent] Failed to create OVS patch port. Cannot have tunneling enabled on this agent, since this version of OVS does not support tunnels or patch ports. Agent terminated!

Environment: Server: 3 UCS blade servers, B-series blade server. OS: Ubuntu precise (12.04.2 LTS) OpenStack version: Grizzly, quantum. Quantum plugin: openvswitch, with GRE I follow this document to install: https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst Network environment: Control Node: eth0 (API network) (10.246.60.55), eth1(mgmt) (192.168.0.1), eth2(VM network) (192.168.100.1) Network Node: eth0 (External network) (10.246.60.56), eth1 (192.168.0.2), eth2 (192.168.100.2) Compute Node: eth0 (just for my login)(10.246.60.57), eth1 (192.168.0.3), eth2 (192.168.100.3)

Hasn't anyone encountered same issue?

I did encounter this issue and still searching for the write solution. It looks like there is some debian mismatch issue seen recently. I have workaround for now:

On Reboot, the ip addr does not show OpenVswitch bridges

root@computenode1:~# ovs-vsctl show

To fix the issue

Set the date correctly date MMDDHHMM

Uninstall the following modules apt-get remove openvswitch-switch openvswitch-datapath-dkms quantum-plugin-openvswitch-agent

Reboot apt-get install openvswitch-switch openvswitch-datapath-dkms quantum-plugin-openvswitch-agent

Reboot

Thanks for the workaround. It really works! Thanks again.

Just figured out the right way to fix this. After doing apt-get update, apt-get upgrade and apt-get dist-upgrade, we must reboot the node. And, the continue applying the next steps.

I'm having the same issue. I reboot the node after apt-get dist-upgrade. I can't get quantum-plugin-openvswitch-agent running.

[quantum.plugins.openvswitch.agent.ovs_quantum_agent] Failed to create OVS patch port. Cannot have tunneling enabled on this agent, since this version of OVS does not support tunnels or patch ports. Agent terminated!

Check https://ask.openstack.org/en/question/1427/ovs-plugin-error-failed-to-create-ovs-patch-port/

[educhoko91]

Posibble solution run the command: service openvswitch-switch force-reload-kmod

I have a 3 node PoC setup (controller,compute,network) with grizzly release on ubuntu 12.04. I am also facing the same issue. I tried the solution mentioned by hrushig & educhoko91 but its still not working.

This is a kernel issue, try downgrading to 3.5.0-41, the reinstall the module

[kmadac]

Here is what helped me to me. Download openvswitch-datapath package from Raring and compile it:

# cd /tmp
# wget http://launchpadlibrarian.net/132679950/openvswitch-datapath-source_1.9.0-0ubuntu1_all.deb
# dpkg -i openvswitch-datapath-source_1.9.0-0ubuntu1_all.deb

# cd /lib/modules/`uname -r`/build/include/linux
# ln -s ../generated/uapi/linux/version.h .

# module-assistant auto-install openvswitch-datapath

@educhoko91 's solution did work! I know it's a kernel problem. I'm using Ubuntu 12.04.4, which kernel version is 3.11, but Grizzly version was only support to 2.6-3.5

Newer version of openstack is better...
