Subject: [dpdk-dev] basic forwarding example not working
Date: Tue, 19 Apr 2016 21:30:09 +0530	[thread overview]
Message-ID: <CAFSK5y3HW8S29Ef9uAf4CgCTe6n1LqLk7x=bFAytN=YYTQhWSQ@mail.gmail.com> (raw)

I am using two virtio network adapter on VM on KVM host.

As  in following output, I have bound both interface with igb_uio driver

./dpdk_nic_bind.py --bind=igb_uio 00:0a.0
./dpdk_nic_bind.py --bind=igb_uio 00:0b.0

[root@localhost tools]# ./dpdk_nic_bind.py --status

But when I run basic fowarding example from skeleton, I get following error
