Topology is 2 Simple ports with a Single

Error what we see here :

not open network device dpdk1 (Address family not supported by protocol)"
Did you bind the physical ports to a dpdk compatible driver?
If you refer to both topologies as the same, why in one case you use
dpdk ports and in the other you use dpdkvhostuser ports.
Same Topology with OVS-DPDK package
installed on Ubuntu 16.04:
add-br br0 -- set bridge br0 datapath_type=netdev
add-port br0 vhost-user1 -- set Interface vhost-user1 type=dpdkvhostuser
add-port br0 vhost-user2 -- set Interface vhost-user2 type=dpdkvhostuser
Error which we see here is : "qemu-system-x86_64:
unable to map backing store for hugepages:
I am not an expert about vhost-user, however when I used it I use
-numa node,memdev=mem -mem-prealloc" as command line.
Is the size parameter correct in your case?
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.
