Since Ubuntu 12.04, we've shipped a number of different Open vSwitch versions supporting various different kernels in various different ways; I thought it was about time that the options were summarized to enable users to make the right choice for their deployment requirements.
Open vSwitch for Ubuntu 14.04 LTS
Ubuntu 14.04 LTS will be the first Ubuntu release to ship with in-tree kernel support for Open vSwitch with GRE and VXLAN overlay networking – all provided by the 3.13 Linux kernel. GRE and VXLAN are two of the tunnelling protocols used by OpenStack Networking (Neutron) to provide logical separation between tenants within an OpenStack Cloud.
This is great news from an end-user perspective as the requirement to use the openvswitch-datapath-dkms package disappears as everything should just *work* with the default Open vSwitch module. This allows us to have much more integrated testing of Open vSwitch as part of every kernel update that we will release for the 3.13 kernel going forward.
You'll still need the userspace tooling to operate Open vSwitch; for Ubuntu 14.04 this will be the 2.0.1 release of Open vSwitch.
