[dpdk-dev] Can we run KNI under a container

[dpdk-dev] Can we run KNI under a container

[chetan bhasin]

Hello Everyone,

We can run dpdk app with KNI on container with below options -
* --network host --privileged* -v /sys/bus/pci/drivers:/sys/bus/pci/drivers
-v /sys/kernel/mm/hugepages:/sys/kernel/mm/hugepages -v
/sys/devices/system/node:/sys/devices/system/node -v /dev:/dev

Is there any way we could run DPDK KNI without --network-host in privileged
mode ?

Please suggest

Thanks,
Chetan
