I’ve been struggling trying to set up the OVS 2.0 with Mininet 2.2 on Ubuntu 12.04.
Apparently the installation script from Mininet is not fully working on Ubuntu 12.04.
What did I do to fix it?
The easiest way to install it is to use the Mininet installation script and then do a small fix.
I did this exactly to install:
sudo apt-get update
sudo apt-get install -y git
git clone git://github.com/mininet/mininet
cd mininet
git checkout -b 2.2.0 2.2.0
util/install.sh -nf
util/install.sh -V 2.3.0
After this you will some weird errors. It should look like this:
Setting up openvswitch-switch (2.3.0-1) ...
* Inserting openvswitch module
* /etc/openvswitch/conf.db does not exist
* Creating empty database /etc/openvswitch/conf.db
* Starting ovsdb-server

You should interrupt the script now with ctrl+C. Next do this:
cd ~/openvswitch/openvswitch-2.3.0/
sudo -s
ovsdb-tool create /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema
ovsdb-server -v --remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=db:Open_vSwitch,SSL,certificate \
--pidfile --detach --log-file
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach
ovs-vsctl show
This partially solves the problem. Let’s go ahead and test it: sudo mn --test pingall.
If you reboot you are going to have the same error. What you can do is to run this everytime you reboot:
cd ~/openvswitch/openvswitch-2.3.0/
sudo -s
ovsdb-tool convert /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema
ovsdb-server -v --remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=db:Open_vSwitch,SSL,certificate \
--pidfile --detach --log-file
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach
ovs-vsctl show
