Installing openvswitch

Hi,

I am new to the Yocto project. Could someone please give me information on how to install openvswitch ? I have already done the same in other Linux OSs but no idea on how to do the same for Yocto.

Thanks,
Monica

The meta-virtualization layer (
http://layers.openembedded.org/layerindex/branch/master/layer/meta-virtualization/)
has a recipe for openvswitch, so add that to your bblayers.conf and add the
packages you need to your image.

Hi Ross,

I see the following files under /meta-virtualization/recipes-networking/openvswitch/:

-        files/

-        openvswitch_1.10.0.bb

-        openvswitch_2.0.0.bb

So, I just went to /repo/poky/build/conf/bblayers.conf and the following line is already present there:
  /data/users/mrajase/ulp/repo/poky/meta-virtualization \

Doesn’t that include the openvswitch folder as well? If it is, what else do I need to add/change?

Thanks,
Monica

You need to actually add the packages that you want to your image.

Okay thanks. I’m assuming by packages you mean the various dependency packages for openvswitch.

And, once I add and bring up the image, do I just start ovs by the usual procedure or is the procedure different ?

Thanks,
Monica

Thanks for the info. It worked once I added the openvswitch package using image_install.

Please excuse if this seems to be a very basic question. I am completely new to yocto.

I have openvswitch package installed in my image. But, I do not see a folder called “openvswitch-2.xx” with all the source code at all! I need the code to make changes. I see these:


-        find -iname "openvswitch*"
./run/openvswitch
./usr/local/etc/openvswitch
./usr/lib/libvirt/ptest/tests/networkxml2xmlupdateout/openvswitch-net-modified.xml
./usr/lib/libvirt/ptest/tests/networkxml2xmlupdateout/openvswitch-net-without-alice.xml
./usr/lib/libvirt/ptest/tests/networkxml2xmlupdateout/openvswitch-net-more-portgroups.xml
./usr/lib/libvirt/ptest/tests/networkxml2xmlout/openvswitch-net.xml
./usr/lib/libvirt/ptest/tests/networkxml2xmlin/openvswitch-net.xml
./usr/lib/openvswitch
./usr/share/openvswitch
./usr/share/openvswitch/bugtool-plugins/system-configuration/openvswitch.xml
./usr/share/openvswitch/bugtool-plugins/system-logs/openvswitch.xml
./usr/share/openvswitch/bugtool-plugins/kernel-info/openvswitch.xml
./usr/share/openvswitch/bugtool-plugins/network-status/openvswitch.xml
./usr/include/linux/openvswitch.h
./etc/openvswitch-controller
./etc/default/openvswitch-controller
./etc/default/openvswitch-switch
./etc/init.d/openvswitch-controller
./etc/init.d/openvswitch-switch
./etc/openvswitch
./var/lib/openvswitch
./var/log/openvswitch

But they don’t have the code. Any help ?

Thanks,
Monica

You installed binary packages, not the sources.

If you want to edit and compile openvswitch on the target then just fetch
it using git and edit/compile/install using gcc and so on (adding tools-sdk
to IMAGE_FEATURES will give you a full toolchain to get this started).

Alternatively you can use devtool to edit on your build machine and deploy
updated binaries to your target.  The Development Manual covers this,
http://www.yoctoproject.org/docs/2.1/dev-manual/dev-manual.html#devtool-use-devtool-modify-to-enable-work-on-code-associated-with-an-existing-recipe
.
