Hi Valentin, would you be willing to share your modified drivers of openvswitch + iptables?
For OpenNebula 3.8 we are going to release a firewall implementation using openflow in the openvswitch driver, but we'd like to also evaluate the other iptables option. Thanks a lot! cheers, Jaime On Wed, Oct 10, 2012 at 6:36 PM, Valentin Bud <[email protected]> wrote: > > > On Wed, Oct 10, 2012 at 7:25 PM, Ruben S.
