First of all thanks for replying to this thread, Mauricio. To give a gist of the activities done for OVS-DPDK installation , here are the details:
1. As part of the Installation guide ( https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md ) we started with installing / Configuring DPDK Target followed with the OVS installation/configuration and compiling binded with the DPDK Target as been explained in the above reference File. .P.S. There were no issues seen while configuring OVS with DPDK . 2. As we understand from the Configuration file " $DPDK_DIR/config/common_linuxapp " VHOST_USER is support for the DPDK CONFIG_RTE_LIBRTE_VHOST=y` CONFIG_RTE_LIBRTE_VHOST_USER=y 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 So in order to test the given topology with the a 2 port on a single bridge and got the following errors as shown below : 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)" 3. Referred webpage(https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200) to overcome this issue on the DPDK dependency with the Kernel modules but it is still not yet resolved. 4. Secondly i have upgraded my Linux Container (Ubuntu 16.04) and installed the default package : openvswitch-switch-dpdkto leverage the application to work with DPDK. Referred the following link to create the VM's using the QEMU-KVM applications : https://software.intel.com/en-us/articles/using-open-vswitch-with-dpdk-on-ubuntu With this the VHOST-USER's are getting created successfully as expected but on creating the VM's currently encountered with the following Error: "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: > Command issued : sudo qemu-system-x86_64 -m 512 -smp 4 -cpu host -hda /home/user/f21vm1c1.qcow2 -boot c -enable-kvm -no-reboot -nographic -net none -chardev socket,id=char1,path=/run/openvswitch/vhost-user1 -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce -device virtio-net-pci,mac=00:00:00:00:00:01,netdev=mynet1 -device virtio-net-pci,mac=00:00:00:00:00:01,netdev=mynet1 -object memory-backend-file,id=mem,size=512M,mem-path=/dev/hugepages,share=on -numa node,memdev=mem -mem-prealloc P.S. We have increased the Hugepages accordingly but the issue isn't resolved yet. Could you provide more information or some relevant links so that we can create the required Topology with DPDK package (with manual Installation as done in Step -1 to 3) or there is a better way to create the VM's or topology with Step-4 (as using the OVS-DPDK package with Ubuntu 16.04). Appreciate a help for the same. ----- Original Message ----- From: Mauricio Vasquez <mauricio.vasq...@polito.it> To: Lakshmi Kotla/HYD/TCS <lakshmi.ko...@tcs.com>, b...@openvswitch.org Cc: poonam ghosh <poonam.gh...@tcs.com> Sent: Tue, 13 Sep 2016 22:19:14 +0530 (IST) Subject: Re: [ovs-discuss] Errors while installing in dpdk in ubuntu 14.04 Hello Lakshmi, On 09/13/2016 12:08 PM, Lakshmi Kotla/HYD/TCS wrote: Dear sir, This is the error that i have encountered when i was trying to install dpdk.

It is really hard to help you without a minimum of information.
