Abstract
========
This document compiles the release notes for the Euphrates release of
OPNFV SFC
Important notes
===============
These notes provide release information for the use of SFC with the
Apex installer and xci tools for the Euphrates release of OPNFV.
Summary
=======
The goal of the SFC Euphrates release is to integrate the OpenDaylight
SFC project into an OPNFV environment, with either the Apex installer or
xci tools. In subsequent releases, we expect Compass4NFV to integrate
the SFC scenarios too.
More information about OpenDaylight and SFC can be found here.

Known Limitations, Issues and Workarounds
=========================================
System Limitations
------------------
The Euphrates 2.0 release has a few limitations:
1 - The testcase sfc_two_chains_SSH_and_HTTP is disabled in this release due to
bugs in ODL, Tacker and networking-sfc:
https://bugs.opendaylight.org/show_bug.cgi?id=9221
https://bugs.launchpad.net/tacker/+bug/1719839
https://bugs.launchpad.net/tacker/+bug/1719876
https://bugs.launchpad.net/networking-sfc/+bug/1719835
https://bugs.launchpad.net/networking-sfc/+bug/1719883
2 - The topology CLIENT_SERVER_SAME_HOST does not work due to a bug in the
vxlan_tool. This tool is part of the ODL-SFC repo and provides support for
non-NSH-aware SFs:
https://bugs.opendaylight.org/show_bug.cgi?id=9219
3 - The topologies CLIENT_SERVER_DIFFERENT_HOST_SPLIT_VNF and
CLIENT_SERVER_SAME_HOST_SPLIT_VNF do not work because of a ODL bug:
https://bugs.opendaylight.org/show_bug.cgi?id=9220
Known issues
------------
1 - 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).
2 - Due to a bug in tacker:
https://bugs.launchpad.net/tacker/+bug/1719841
it is not possible to run the SFC scenarios in openstack environments
which require SSL connections to public endpoints and use self-signed
certificates
Workarounds
-----------
There is a way to avoid the known issue number 2 when using xci. Once
the deployment is successfully done, go to tacker server and modify
line 242 of the file:
/openstack/venvs/tacker-15.1.7/lib/python2.7/site-packages/keystoneauth1/session.py
So that instead of having:
self.verify = verify
It has:
self.verify = False
Forcing tacker to not check the certificates
Test results
============
The Euphrates release of SFC has undergone QA test runs
with Functest tests on the Apex installer and xci utility
