A: The following table lists the Linux kernel versions against which the
given versions of the Open vSwitch kernel module will successfully
build. The Linux kernel versions are upstream kernel versions, so
- modified Linux kernels modified from the upstream sources may not
- build in some cases even if they are based on a supported version.
- This is most notably true of Red Hat Enterprise Linux (RHEL) kernels,
- which are extensively modified from upstream.

Open vSwitch Linux kernel
------------ -------------
1.6.x 2.6.18 to 3.2
1.7.x 2.6.18 to 3.3
1.8.x 2.6.18 to 3.4
- 1.9.x 2.6.18 to 3.6
+ 1.9.x 2.6.18 to 3.7
Open vSwitch userspace should also work with the Linux kernel module
built into Linux 3.3 and later.
A: The kernel module in upstream Linux 3.3 and later does not include
the following features:
- - Bridge compatibility, that is, support for the ovs-brcompatd
- daemon that (if you enable it) lets "brctl" and other Linux
- bridge tools transparently work with Open vSwitch instead.
-
- We do not expect bridge compatibility to ever be available in
- upstream Linux. If you need bridge compatibility, use the
- kernel module from the Open vSwitch distribution instead of the
- upstream Linux kernel module.
-
- Tunnel virtual ports, that is, interfaces with type "gre",
"ipsec_gre", "capwap". It is possible to create tunnels in
Linux and attach them to Open vSwitch as system devices.
