Description Andrew Lau 2014-03-29 00:02:56 UTC

Description of problem:
Post Nova (Neutron) deploy, the puppet module will execute successfully, however after an instance is created on the next puppet run the firewall module will complain because openvswitch has created some new rules:

Puppet Output:

Comment 1 Allan St. George 2014-03-31 11:38:25 UTC

This also occurs with OpenStack Havana.

Comment 2 John Eckersberg 2014-04-03 20:16:30 UTC

This is the upstream pull request to fix this problem - https://github.com/puppetlabs/puppetlabs-firewall/pull/337

Still a work in progress, but looks close to being done.  I'll help out upstream however I can to speed it along.

Comment 3 Edouard Bourguignon 2014-04-16 14:27:40 UTC

same problem on icehouse

Comment 4 btaylor 2014-05-29 14:05:08 UTC

just ran into this also after I updated the masquerade rule to use br-ex instead of eth0

Comment 5 Nilesh Patil 2014-07-18 10:48:55 UTC

Is it still a open bug? I am seeing this issue on our production openstack instance. 

Willing to help in case you need access to box. 

Regards,
Nilesh

Comment 6 John Eckersberg 2014-07-18 12:57:06 UTC

This is still waiting to be merged upstream, at which point the next rebase of the firewall module will pull it into RDO.  Alternatively we can carry the patch ourselves but I'd rather just get it upstreamed.  I have offered virtual cookies in the pull request as incentive to try and move it along.

Comment 7 Lars Kellogg-Stedman 2015-03-20 20:59:07 UTC

https://github.com/puppetlabs/puppetlabs-firewall/pull/337 was merged on July 26, 2014, and the fix is included in the RDO Icehouse (and later) packages.
