Basically, what I'm trying to do, is to run OVS+DPDK at the host, and also, inside of a KVM Guest, with multi-queue, but it doesn't work and crashes. Soon as you enable multi-queue at the guest, it crashes the OVS of the host! OVS+DPDK segfault at the host, after running "ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=4" within a KVM Guest: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1577088 Thanks!
