KNI automatic IP configuration

KNI automatic IP configuration

[Olivier Deme]

Hi all,

Is it possible on Linux to get the Linux network manager to automatically configure a KNI virtual network interface as soon as it comes up?
I haven’t been able to get Fedora to apply the configuration under /etc/sysconfig/network-scripts/ifcfg-veth0 file upon starting my DPDK application.

Executing ifup veth0 manually works but somehow the fedora network manager seems to have an issue to apply the if cfg config automatically.
In the system logs I can see something along the lines “kni doesn’t support ethtool”. Is this related?

I also tried ifplugd but without success.

Many thanks for your help,

Olivier.

Which NIC device are you using now?

KNI does not provide Ethtool support for all NICs supported by the Poll-Mode Drivers.

Currently I’m using the e1000 PMD driver.

Thanks,
Olivier.

e1000 driver supports many different NIC devices. 

Do you know your NIC device type or device_id?

Hi, sorry to resurrect this question.
I am now using a virtio network interface in a qemu VM.
Is it possible to use ifplugd to automatically setup the IP 
configuration of a KNI based interface?
Here is the output of lspci:
00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
00:04.0 Ethernet controller: Red Hat, Inc Virtio network device
00:05.0 Ethernet controller: Red Hat, Inc Virtio network device
00:06.0 Ethernet controller: Red Hat, Inc Virtio network device

Thanks for your help.
Olivier.
