At present you can use ivshmem or vhost-cuse. The instructions for ivshmem are in INSTALL.DPDK

If you want info about the differences between ivshmem and vhost - have a look at the video from the OVS conf http://youtu.be/FmQmo8zG4y8 > > Thank you in advanced. > > Iñaki Murillo > > > > > _______________________________________________ > discuss mailing list > [email protected] > http://openvswitch.org/mailman/listinfo/discuss _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
