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.
