libssl is installed, then Open vSwitch will automatically build
with support for it.
- - Python 2.x, for x >= 4.
+ - libcap-ng, written by Steve Grubb, is optional but recommended. It
+ is required to run OVS daemons as a non-root user with dropped root
+ privileges. If libcap-ng is installed, then Open vSwitch will
+ automatically build with support for it.
- - patch (The utility that is used to patch files).
+ - Python 2.7.
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
- Perl. Version 5.10.1 is known to work. Earlier versions should
also work.
- - Python 2.x, for x >= 4.

If you are going to extensively modify Open vSwitch, please consider
installing the following to obtain better warnings:
`% ./configure CFLAGS="-g -O2 -mssse3"`
+Note that these CFLAGS are not applied when building the Linux
+kernel module. Custom CFLAGS for the kernel module are supplied
+using the EXTRA_CFLAGS variable when running make. So, for example:
+
+ `% make EXTRA_CFLAGS="-Wno-error=date-time"
+
To build the Linux kernel module, so that you can run the
kernel-based switch, pass the location of the kernel build
directory on --with-linux. For example, to build for a running
./boot.sh
vagrant provision --provision-with configure_ovs,install_rpm
+Two provisioners are included to run system tests with the OVS kernel
+module or with a userspace datapath. This tests are different from
+the self-tests mentioned above. To run them:
+
+ ./boot.sh
+ vagrant provision --provision-with configure_ovs,test_ovs_kmod,test_ovs_system_userspace
+
