Of so you need to replicate the same traffic form the same interface to 3 VM, got it. Please note you cannot use ZC drivers because your card is not supported (Intel only at the moment), however you can still use ZC to distribute traffic across VMs. In this case you need pf_ring on both host and guest systems, please have a look at https://github.com/ntop/PF_RING/blob/dev/userland/examples_zc/README.kvm
