[dpdk-users] DPDK NIC is unreachable

[dpdk-users] DPDK NIC is unreachable

[Priyanka]

Hi,

We have a SRIOV+ DPDK 16.04 setup for a VM using KVM-qemu hypervisor. We 
are unable to ping the VM. We are assigning the VM to a SRIOV vf and for 
the DPDK enabled NIC on the VM  to detect this VF, we are using KNI.

We used the KNI app available in the examples folder.  Although the non 
DPDK NIC is reachable in the VM but once we assign an IP using KNI to 
the DPDK NIC of the VM, it is unreachable.

Please help us solve this issue.

Thanks,

Priyanka

Removing dev mail list.

Can you please give some information related setup, is following correct:

Host: Interface controlled by Linux (H1)
VM: There are two VF's, one controlled by DPDK (G1), other by Linux (G2)
NIC: ?

KNI sample application ruun on VM.

You can ping from H1 to G2, but not H1 to G1?

Hi Ferruh,

Thanks for the reply. We could resolve this issue. The problem was that 
the kni command  we were using was incorrect.

Thanks,

Priyanka
