Description Dan Sneddon 2015-06-16 20:47:49 UTC
Description of problem:
The net-config-bridge.yaml template is used for both Controller and Compute, resulting in a br-ex being set up on the compute host, even though it is unused.

Version-Release number of selected component (if applicable):
All versions prior to the poodles created on June 16, 2015

How reproducible:

Steps to Reproduce:
1. Deploy overcloud

Actual results:
Compute nodes attached to external bridge

Expected results:
Compute nodes should not be attached to external bridge

Additional info:
This should have been fixed in the latest poodles. This can be confirmed by making sure that the compute nodes do not have a br-ex after deployment.

Comment 3 Marios Andreou 2015-06-18 14:24:21 UTC
so Dan I tracked down the review @ https://review.openstack.org/#/c/190849/ 

fyi I have a fresh env with latest poodle and it seems that today that change hasn't yet been merged into downstream tht

(my compute still has a br-ex and the tht downstream repo that i am using for roles gives nothing for git log | grep "external bridge" )

I deploy (network isolation) RHEL-OSP director puddle 7.0 RC puddle 2015-06-29-1

$ sudo  rpm -qa |grep neutron
[stack@instack ~]$ rpm -qa |grep heat

1. When I connect to compute node that's what I see.
it's looks like compute nodes still connected to external net/bridge.
2. Some can explain what is those vlans (20,30,50)?

Actually, it looks like you just validated that the bug is fixed.

VLAN 10 is the external network VLAN, and I don't see that here on the compute node. VLAN 20 is the Internal API, VLAN 30 is Storage, and VLAN 50 is the Tenant network (GRE and VXLAN will use this network for tunneling traffic).

These default VLANs come from the NIC configurations in /usr/share/openstack-tripleo-heat-templates/network/config/single-nic-with-vlans/.

Comment 9 Dan Sneddon 2015-07-02 20:45:17 UTC
(In reply to Dan Sneddon from comment #8)

Some of the confusion is probably because the bridge defaulted to being called "br-ex" on the compute node. That is something we can fix in future versions of the template, we'll probably call it "br-vlan" to avoid confusion. I don't think that needs a separate bug, because it'll be included in the updates that are already underway.

Comment 10 Eran Kuris 2015-07-05 06:31:09 UTC
Thanks Dan . It would be great if the name will be update to "br-vlan"  instead  
  "br-ex" .
