Fixed In Version: os-net-config-0.2.2-1.el7ost
Doc Type: Bug Fix
Doc Text:
When using Linux kernel mode for bridges and bonds (as opposed to Open vSwitch), the physical device was not detected for the VLAN interfaces. This, in turn, prevented the VLAN interfaces from working correctly. With this release, the os-net-config utility automatically detects the physical interface for a VLAN as long as the VLAN is a member of the physical bridge (that is, the VLAN must be in the 'members:' section of the bridge). As such, VLAN interfaces now work properly with both OVS bridges and Linux kernel bridges.

Description Dan Sneddon 2016-03-21 18:00:03 UTC 
Description of problem:
When using Linux bonds along with the Big Switch 3rd-party Neutron drivers, the physical device of the bond is not properly detected. There is a workaround that involves specifying the device on the VLANs, but this only works if all nodes have the same NIC config. In instances where the nic abstractions are used, this workaround does not work.

Version-Release number of selected component (if applicable):
OSP 8 beta puddle

How reproducible:
100%

Steps to Reproduce:
1. Configure NIC templates with NIC abtractions (nic1, nic2...)
2. Deploy with Linux bonds and the Big Switch driver
3.

Actual results:
The VLANs are not detected properly as being part of the bond, and the PHYSDEV is not set properly in the config files.

Expected results:
The VLANs should be properly detected and added to the Linux bond
