Rubygem-staypuft: Neutron deployment with vxlan doesn't configure br-ex on the neutron-networker, As results instances won't be able get outside the network.


When attempting to deploy Non-HA-neutron with vxlan , staypuft doesn't configure br-ex on the neutron-networker. 
from looking at the neutron-networker YAML.file (view from the staypuft GUI ) it looks like there's -->  external_network_bridge: br-ex .
but the actual result when running 'ovs-vsctl show' on the neutron-networker it doesn't show that the br-ex exist.

Neutron-Networker :

Comment 4 Jason Guiditta 2014-07-22 21:34:48 UTC
This appears to be similar but not exactly the same as:

Both related to how puppet-neutron and puppet-vswitch work together to create the bridge.  Previously, vswitch code was not correctly moving the IP, and now it appears to not be creating the bridge at all. I believe packstack does not run into either issue because they explicitly create the bridge file.  However, the 2 puppet modules purport to do so, and we have changed nothing in quickstack, so adding a fix there is not the appropriate response, in my opinion.  neutron or vswitch should create these files if they do not exist, otherwise, any project using those modules will need to recreate the file manually, which is sub-optimal at best.

I discussed this with Mike, and feel that the fix should be in openstack-puppet-modules, if someone disagrees, we can discuss.

Comment 9 Ramon Acedo 2014-08-24 13:04:55 UTC
I confirm this still happens in the GA announced on 22 Aug (rhel-osp-installer-0.1.10-2.el6ost.noarch).

The workaround is to edit the Neutron Networker host and in Parameters override "external_network_bridge" and set it to "br-ex".

That way the L3 agent will add the qg-xxx interface from the router to br-ex as expected.

I think this value should be set by Staypuft when in the OpenStack Installer Setup Wizard "Configure external interface on network node" is checked.

Comment 10 Gilles Dubreuil 2014-08-26 06:45:47 UTC
Puppet-vswitch doesn't behave properly on RHEL6 because of Ruby version match method (REGEX) doesn't support use of a block.

This has been addressed upstream with patch 18

Comment 11 Gilles Dubreuil 2014-08-26 07:48:01 UTC
Validated integration test using patch 18 which behaves as intended.

Although I had to restart network service by hand, seems like the ifdown/ifup sequence didn't catch br-ex.

Comment 12 Gilles Dubreuil 2014-08-28 01:51:16 UTC
Patch 19 changes the ifdown/ifup order so br-ex (default) comes up on rhel6

Comment 13 Gilles Dubreuil 2014-09-01 05:54:45 UTC
Patch 20 works around dynamic interface detection on rhel6
