-To compile the kernel module on Linux, you must also install the
-following. If you cannot build or install the kernel module, you may
-use the userspace-only implementation, at a cost in performance. The
-userspace implementation may also lack some features. Refer to
-INSTALL.userspace for more information.
+On Linux, you may choose to compile the kernel module that comes with
+the Open vSwitch distribution or to use the kernel module built into
+the Linux kernel (version 3.3 or later). See the FAQ question "What
+features are not available in the Open vSwitch kernel datapath that
+ships as part of the upstream Linux kernel?" for more information on
+this trade-off. You may also use the userspace-only implementation,
+at some cost in features and performance (see INSTALL.userspace for

+install the following:
- A supported Linux kernel version. Please refer to README for a
list of supported versions.
Before starting ovs-vswitchd itself, you need to start its
configuration database, ovsdb-server. Each machine on which Open
vSwitch is installed should run its own copy of ovsdb-server.
