Does a network device named "test-test" exist?

[Fangfenghua]

When i use version 1.11.0, command ovs-vsctl add-port .... if the port doesn't exist,it will create the port and then add to bridge.

Ref:http://openvswitch.org/support/dist-docs-2.5/ovs-vsctl.8.html

ovs-vsctl did create the port and add it to the bridge.

Hello,

I have a similar issue going with ovs 2.5 on Linux version 4.2 (running on a VM)

root@cep-VirtualBox:/usr/src/ovs/ovs-2.5.0# ovs-vsctl add-port br0 ovs-p0 -- set interface ovs-p0 external-ids:iface-id="p0"
ovs-vsctl: Error detected while setting up 'ovs-p0'. See ovs-vswitchd log for details.
root@cep-VirtualBox:/usr/src/ovs/ovs-2.5.0# ovs-vsctl show
2d64f0cf-c294-44f1-8228-0f367c879b3d
Bridge "br0"
Port "br0"
Interface "br0"
type: internal
Port "ovs-p0"
Interface "ovs-p0"
error: "could not open network device ovs-p0 (No such device)"

Any pointers whatsoever will be helpful.

so does i meet that problem, i use ovs2.6.1 and dpdk 16.11.2

    2017-08-23T09:35:19.411Z|00065|bridge|WARN|could not open network device dpdk-p0 (No such device)
    2017-08-23T09:35:34.819Z|00066|bridge|WARN|could not open network device dpdk-p0 (No such device)

are you solve this problem?

The port‘s name should be a exist interface use ifconfig to see, such as eth0. If you just want to use a virtual port name to make a test you should specify the port's type like ovs-vsctl add-port br0 port0 -- set Interface port0 type=internal or ovs-vsctl set Interface port0 type=internal

I am seeing the same issues.

I tried with ovs-vsctl add-port br0 -- set Interface type=dpdk options:dpdk-devargs=0000:00:09.0

With this, I am seeing the same issue. Please let me know, if anyone has resolved this issue. I am using dpdk 16.07.2 with ovs 2.6.1

Thanks

Arbitrary port names for DPDK ports was only introduced in OVS 2.7. For OVS 2.6 the DPDK port name must be "dpdkn" where n corresponds to the dpdk port as it was added to the userspace driver. Also for 2.6 you should not include the devargs argument for the bus slot function.

You should add the port with the following command instead

ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk

To add a second port use

ovs-vsctl add-port br0 dpdk1 -- set Interface dpdk1 type=dpdk

Further details can be found in the OVS 2.6 Docs.

Thanks for the information.

Here is the hw info for the ports

../dpdk-stable-16.07.2/tools/dpdk-devbind.py --status

Network devices using DPDK-compatible driver

0000:00:09.0 '82540EM Gigabit Ethernet Controller' drv=igb_uio unused=
0000:00:0a.0 '82540EM Gigabit Ethernet Controller' drv=igb_uio unused=

How does each port map to corresponding port (Ex: how does dpdk0 map to 0000:00:09.0)

Thanks

[istokes]

I believe they map in the order they appear in status above. So in this case dpdk0 correspond to 00:09.0. You can confirm this by adding and removing the devices from the igb_uio driver in different orders and testing with ovs-dpdk each time.

However, this method is quite unwieldy in practice, I would encourage you to move to OVS 2.7 at the very least as 2.6 is quite old & support for DPDK was still only experimental at this point in OVS.

Why it shows Port does not contain a column whose name matches "set"

The port‘s name should be a exist interface use ifconfig to see, such as eth0. If you just want to use a virtual port name to make a test you should specify the port's type like ovs-vsctl add-port br0 port0 -- set Interface port0 type=internal or ovs-vsctl set Interface port0 type=internal
