[ovs-discuss] networking-ovs-dpdk on ubuntu

[Rapelly, Varun]

Hi All,

I'm trying to install networking-ovs-dpdk with openstack (devstack) on Ubuntu 14.04 (3.13 kernel) on a single node.

Used following steps:

1.       echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

2.       apt-get install sudo -y

3.       apt-get install sudo -y || yum install -y sudo

4.       sudo apt-get install git -y || sudo yum install -y git

5.       git clone https://git.openstack.org/openstack-dev/devstack

6.       cd devstack

7.       ./stack.sh

stack at ubuntu:~/devstack$ ifconfig
eth0      Link encap:Ethernet  HWaddr 52:55:00:00:00:01
          inet addr:10.54.218.56  Bcast:10.54.218.255  Mask:255.255.255.0
          inet6 addr: fe80::5055:ff:fe00:1/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:104 errors:0 dropped:0 overruns:0 frame:0
          TX packets:102 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:10537 (10.5 KB)  TX bytes:14847 (14.8 KB)

I have two other eth1,2 ports on the machine.

I used https://github.com/openstack/networking-ovs-dpdk/blob/master/doc/source/_downloads/local.conf.single_node file as local.conf<https://github.com/openstack/networking-ovs-dpdk/blob/master/doc/source/_downloads/local.conf.single_node%20file%20as%20local.conf> and copied the
same to devstack directory and updated with following details.

I'm facing problem with following configuration.

stack at ubuntu:~/devstack$ cat local.conf
#All in one single node config
[[local|localrc]]
HOST_IP_IFACE=eth0
HOST_IP=10.54.218.56
OVS_BRIDGE_MAPPINGS="default:br-eth0"

With the above configuration, I'm loosing the management connection of the host.

Log shows:

Please let me know:

1.       Do we need to update any other files along with copying local.conf to devstack directory?

2.       In OVS_BRIDGE_MAPPINGS="default:br-eth0", do I need to change the interface to some other interface?

3.       I would like to build DPDK with "x86_64-native-linuxapp-gcc", where should I update this?

4.       I would like to create the ovs-dpdk vhostuser ports, with the other two eth ports, ie.., eth1 & eth2. Where should I update the config for this?

FYI: DPDK: 2.0.0 version OVS: 2.4.0
stack at ubuntu:~/devstack$ uname -a
