However, when I use centos7.0, then l2fwd is able to receive all the packets. 2) I've also seen that on centos7.0, symmetric_mp itself is not working. dev start fails with 280 error. i40evf is giving us lot of headache. The i40evf kernel driver works without any problem. Host is a centos7 KVM. I've already upgraded firmware to latest.
