Thiago: This xen PMD is based on grant table mechanism and virtio interface. Worth to note is it needs customized backend, which now resides in examples/vhost_xen. Another approach is netfront based PMD, which has kernel netback backend in place, but i guess it couldn't achieve best performance as we need map each grant page in backend. Stephen submitted the patch for netfront PMD http://dpdk.org/dev/patchwork/patch/3330/. Thomas, do you know its status? Anyway i will try to create the XEN environment, and check the issues.
