Greetings.

Back to openvswitch - I have done the following in order to get version 1.10 (if you have mininet-2.0.0 already running, please proceed to Stage 2):

Stage 1

- download mininet image 2.0.0 (https://github.com/downloads/mininet/mininet/mininet-2.0.0-113012-amd64-ovf.zip)
- the image is in vmware format I guess, but can by simply imported into virtualbox
- start mininet-2.0.0, login as mininet, password mininet


Stage 2

- uninstall packages openvswitch-common and openvswitch-switch (there should be version 1.4.3 officially in ubuntu repo, so in case of emergency these can be always installed again)
- download latest release of openvswitch: http://openvswitch.org/releases/openvswitch-1.10.0.tar.gz
- there are install howtos, take a look at INSTALL.Debian
- there are some new packages to be installed (apt-get install build-essential fakeroot)
- run dpkg-checkbuilddeps to check, if all dependencies are installed
- here comes the long step 4. from INSTALL.Debian
- if everything compiled successfully, you should have these deb files in parent folder:

openvswitch-common_1.10.0-1_amd64.deb
openvswitch-controller_1.10.0-1_amd64.deb
openvswitch-datapath-dkms_1.10.0-1_all.deb
openvswitch-datapath-source_1.10.0-1_all.deb
openvswitch-dbg_1.10.0-1_amd64.deb
openvswitch-ipsec_1.10.0-1_amd64.deb
openvswitch-pki_1.10.0-1_all.deb
openvswitch-switch_1.10.0-1_amd64.deb
openvswitch-test_1.10.0-1_all.deb
ovsdbmonitor_1.10.0-1_all.deb
python-openvswitch_1.10.0-1_all.deb

- now install
dpkg -i openvswitch-common_1.10.0-1_amd64.deb
dpkg -i openvswitch-switch_1.10.0-1_amd64.deb

- now mininet should be using openvswitch 1.10.0, this can be simply tested by running ODL-controller and let mininet to connect to it.

- to use OF-1.3 following parameter has to be passed to openvswitch startup command:
protocols=OpenFlow13

So I made following change to node.py file (mininet python class, be sure to modify the distributed file, not the one in /home/mininet/mininet/...) in order to control the protocol version using cmd parameter:

or
sudo mn --topo single,3  --controller 'remote,ip=<your controller IP>' --switch ovsk,protocols=OpenFlow13

To test the version of used protocol by switch "s1":

ovs-ofctl -O OpenFlow10 show s1
ovs-ofctl -O OpenFlow13 show s1


If this is useful, I can put it on wiki. If you have any suggestions or improvements, please let me know. The image of virtual machine is huge (3.6 GB), but size of neccessary deb files is only 2 MB, so maybe I can upload them somewhere.
