Linux Bridge Plugin?

[rohagan]

I know the puppet openstack module utilizes OVS as it's default mechanism driver/plugin, is there a way to utilize a Linux Bridge instead of the default OVS mechanism driver/plugin with the puppet openstack module?

Thanks for any input,

The puppetlabs openstack module doesn't currently provide an interface to use Linux Bridge instead of OVS, but it is available in the neutron module. You could design your own profiles that use the neutron::agents::linuxbridge and neutron::plugins::linuxbridge classes.

It looks like there's a parameter in the openstack class for neutron_mechanism_drivers, but that just gets passed to openstack::common::ovs so that's not actually useful. We could try to move openstack::common::ovs to something like openstack::common::ml2 and make the driver actually configurable. I won't be able to get to that refactor any time soon, but I would be happy to look at pull requests for it.

Thank you for writing me back,

This is exactly what I kind of figured, running neuron separately to utilize the linuxbridge,

But again thank you for your response, and a look at a pull request would also be very much appreciated,

Thanks,

Ryan

I also use LinuxBridge instead of OpenvSwitch and made the following changes:

In my .pp file I added the following:

  tenant_network_types  => ['vlan'],
  mechanism_drivers     => ['linuxbridge'],

  enable_security_group => true,
}

  alias  => 'linuxbridge-confdir',
}

file { '/etc/neutron/plugins/linuxbridge/linuxbridge_conf.ini':
  ensure  => link,

}

This is in our backlog here but I don't think we will have the chance to work on it soon. If someone wants to take this on I think it would be reasonably simple to add this support to the module, as @kaazoo demonstrated.

[kaazoo]

By the way, add forked this repository and added optional LinuxBridge support:
https://github.com/kaazoo/puppetlabs-openstack

Might not be fully complete, but works for me so far.
