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

Wed Sep 14 10:02:16 UTC 2016

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.

Dear
  sir,

This is the error that i have encountered when i was trying
  to install dpdk.

  Bridge "bridge0"

          Port "dpdk0"

              Interface "dpdk0"

                  type: dpdk

                  error: "could not open network device dpdk0

          Port "dpdk1"

              Interface "dpdk1"

                  type: dpdkvhost

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

 Could you please provide more information?

 - How did you compile ovs?

 - How did you run ovs?

 - How did you create the bridge and the ports?

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

Thanks and Regards
Lakshmi Kotla
