Abstract
========
This document compiles the release notes for the Colorado release of
OPNFV SFC.
Important notes
===============
These notes provide release information for the use of SFC with the Fuel
and Apex installer tools for the Colorado release of OPNFV.
Summary
=======
The goal of the SFC Colorado release is to integrate the OpenDaylight
SFC project into an OPNFV environment, with either the Fuel or Apex
installer. In subsequent releases, other OPNFV installers will be
considered.
More information about OpenDaylight and SFC can be found here.

Known Limitations, Issues and Workarounds
=========================================
System Limitations
------------------
The Colorado 1.0 release has several limitations:
1 - OPNFV SFC only works in non-HA environments with the Fuel installer.
Tacker is currently not registered in the HA Proxy, so the calls to it fail.
2 - It only works in one-compute deployments. Tacker fixed the
multicompute support in the last weeks but it has not been tested
yet.
3 - The first time a classification rule is created, it does not
work. This is a known issue in Netvirt-ODL. Create the classification
once again and it should work. This issue will be fixed in ODL
Boron SR1, which will be included in Colorado 2.0.
4 - Any VM (e.g. SFs) must have only one security group.
There is a bug in ODL Boron which only one security group is read.
The rest are silently ignored. This issue will be fixed in ODL
Boron SR1, which will be included in Colorado 2.0.
Known issues
------------
OpenDaylight SFC relies on a version of Open vSwitch (OVS) with
Network Service Headers (NSH). A version of OVS with NSH currently
exists, but it is in a branched version of OVS. Extensive upstream
work has been done to merge the NSH patches into mainstream OVS,
but the work is still not complete. More information about this
can be found in the OPNFV SFC design document (link provided above).
Workarounds
-----------
The way OpenStack handles VXLAN-GPE tunnels doesnt work well with
SFC, since OpenStack terminates the VXLAN tunnels in the br-int
bridge instead of the SF VM. Ideally, the tunnel should be terminated
in the VM so the SF has access to the NSH header carried in the tunnel.
A workaround was created to send the packets to the SF VM with the
VXLAN-GPE headers intact and can be found in the OPNFV SFC design
document (link provided above).
Test results
============
The Colorado release of SFC has undergone QA test runs
with Functest tests on the Fuel and Apex installers.
