2012-10-02 Thread Alexey I. Froloff
Hi, While openvswitch does not support InfiniBand natively, it is still possible to use IB features. One can create GRE tunnels with endpoints on IPoverIB interface. Recently I've come to an idea to use RDMA for tunneling packets between hypervisors. Since all tunnels are point to point, one ca
