Open vSwitch
============
Open vSwtich (OVS) is a software switch commonly used in OpenStack deployments
to replace Linux bridges as it offers advantages in terms of mobility, hardware
integration and use by network controllers.
Supported OPNFV Installers
--------------------------
Currently not all installers are supported.
Fuel Installer
~~~~~~~~~~~~~~
OVSNFV project supplies a Fuel Plugin to upgrades Open vSwitch on an OPNFV
installation to use user-space datapath.
As part of the upgrade the following changes are also made:
* change libvirt on compute node to 1.2.12
* change qemu on compute node to 2.2.1
* installs DPDK 2.0.0
* installs OVS 2.1 (specifically git tag 1e77bbe)
* removes existing OVS neutron plugin
* installs new OVS plugin as part of networking_ovs_dpdk OpenStack plugin
version stable/kilo
* work around _set_device_mtu issue
Limitations
~~~~~~~~~~~
This release should be considered experimental. In particular:
* performance will be addressed specifically in subsequent releases.
* OVS and other components are updated only on compute nodes.
Bugs
~~~~
* There may be issues assigning floating and public ip address to VMs.
