Installation Requirements
-------------------------
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-l26. For example, to build for a running
- instance of Linux 2.6:
+ directory on --with-linux. For example, to build for a running
+ instance of Linux:
- % ./configure --with-l26=/lib/modules/`uname -r`/build
+ % ./configure --with-linux=/lib/modules/`uname -r`/build
If you wish to build the kernel module for an architecture other
than the architecture of the machine used for the build, you may
specify the kernel architecture string using the KARCH variable
when invoking the configure script. For example, to build for MIPS
- with Linux 2.6:
+ with Linux:
- % ./configure --with-l26=/path/to/linux-2.6 KARCH=mips
+ % ./configure --with-linux=/path/to/linux KARCH=mips
The configure script accepts a number of other options and honors
additional environment variables. For a full list, invoke
6. If you built kernel modules, you may load them with "insmod", e.g.:
- % insmod datapath/linux-2.6/openvswitch_mod.ko
+ % insmod datapath/linux/openvswitch_mod.ko
You may need to specify a full path to insmod, e.g. /sbin/insmod.
To verify that the modules have been loaded, run "/sbin/lsmod" and
any managers specified in the database itself, and to use the SSL
configuration in the database:
- % ovsdb-server /usr/local/etc/openvswitch/conf.db \
- --remote=punix:/usr/local/var/run/openvswitch/db.sock \
- --remote=db:Open_vSwitch,manager_options \
- --private-key=db:SSL,private_key \
- --certificate=db:SSL,certificate \
- --bootstrap-ca-cert=db:SSL,ca_cert \
- --pidfile --detach
+ % ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
+ --remote=db:Open_vSwitch,manager_options \
+ --private-key=db:SSL,private_key \
+ --certificate=db:SSL,certificate \
+ --bootstrap-ca-cert=db:SSL,ca_cert \
+ --pidfile --detach
+
+(If you built Open vSwitch without SSL support, then omit
+--private-key, --certificate, and --bootstrap-ca-cert.)
Then initialize the database using ovs-vsctl. This is only
necessary the first time after you create the database with
Then start the main Open vSwitch daemon, telling it to connect to the
same Unix domain socket:
- % ovs-vswitchd unix:/usr/local/var/run/openvswitch/db.sock \
- --pidfile --detach
+ % ovs-vswitchd --pidfile --detach
Now you may use ovs-vsctl to set up bridges and other Open vSwitch
features. For example, to create a bridge named br0 and add ports
