Issue enabling tunneling on OVS #8

Closed albertomolina closed 10 years ago

albertomolina commented 10 years ago

After installing and configuring neutron-plugin-openvswitch-agent, this agent is not alive:

root@controller:~# neutron agent-list
+--------------------------------------+--------------------+------------+-------+----------------+
| id                                   | agent_type         | host       | alive | admin_state_up |
+--------------------------------------+--------------------+------------+-------+----------------+
| 484f7b56-e62b-4526-be3b-224e8f2b149a | Open vSwitch agent | controller | xxx   | True           |

And /var/log/neutron/ovs-agent.log shows an error:

2014-06-13 07:22:33.421 4006 ERROR neutron.plugins.openvswitch.agent.ovs_neutron_agent [req-e1954c60-4f16-4b7e-b8a9-5ed8e95fc30b None] 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!

openvswitch module is loaded:

root@controller:~# lsmod |grep openvswitch

Executing neutron-openvswitch-agent from command line instead from init script seems to work properly:

root@controller:~# neutron-openvswitch-agent

Nova and neutron conf files need to be reviewed

Reported to bugs.debian.org:

albertomolina commented 10 years ago

Bug 751714 has been closed, "dkms way" is recommended by Thomas Goirand. I've replied directly to him saying that at this moment dkms fails to build with kernel 3.14

albertomolina commented 10 years ago

The same bug is open at this moment in Ubuntu:

https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1266749

But Ubuntu is using in-tree kernel module instead dkms

albertomolina commented 10 years ago

Next attempt: Using Ubuntu trusty kernel (3.13): http://packages.ubuntu.com/trusty/kernel/linux-image-3.13.0-29-generic

albertomolina commented 10 years ago

After several tests a solution was found: using in-tree openvswitch kernel module with OVS 2.1.0 instead of trying to use dkms out-of-tree module. At this moment OVS 2.1.0 isn't yet in Jessie, we will use packages from sid

albertomolina commented 10 years ago

Now is working properly with in tree module with kernel 3.14 and OVS 2.1.0 from jessie. I'm closing this bug
