[ovs-discuss] Fwd: Re: Errors while installing in dpdk in ubuntu 14.04

[Lakshmi Kotla/HYD/TCS]

Topology is 2 Simple ports with a Single
Bridge  as shown below (with OVS and DPDK installed on Ubuntu 14.04):

ovs-vsctl add-br bridge0
-- set bridge bridge0 datapath_type=netdev

ovs-vsctl add-port bridge0 dpdk0 -- set Interface dpdk0 type=dpdk

ovs-vsctl add-port bridge0 dpdk1 -- set Interface dpdk1 type=dpdk

Error what we see here :
Bridge "bridge0"

        Port "dpdk0"

            Interface "dpdk0"

                type: dpdk

                error: "could
not open network device dpdk0 (Address family not supported by protocol)"


        Port "dpdk1"

            Interface "dpdk1"

                type: dpdk

                error: "could
not open network device dpdk1 (Address family not supported by protocol)"


Same Topology with OVS-DPDK package
installed on Ubuntu 16.04:
 ovs-vsctl
add-br br0 -- set bridge br0 datapath_type=netdev 
ovs-vsctl
add-port br0 vhost-user1 -- set Interface vhost-user1 type=dpdkvhostuser

ovs-vsctl
add-port br0 vhost-user2 -- set Interface vhost-user2 type=dpdkvhostuser

Error which we see here is : "qemu-system-x86_64:
-object

memory-backend-file,id=mem,size=512M,mem-path=/dev/hugepages,share=on:

unable to map backing store for hugepages:  




We need to understand if there is something
which is missed as part of the Hugepages configuration for both the above
installations. Or do you have a better Solution to deal with such basic
topologies with DPDK.

Thanks
