Well, we don't test it, and the libxl toolstack doesn't really help getting virtio devices. > 2. If yes, is there anything wrong in my guest config file? The wiki state that you should add 'xen_emul_unplug=never' to the guest kernel's command line. (That would be "extra" in your guest.cfg.) I think that will prevent the virtio-net device from been unplug, and so you will see the virtio-net device in the guest. But since libxl create Xen PV device anyway, you'll still have the Xen PV NIC, so two NICs with the same MAC. I hope that help, -- Anthony PERARD
