Hi Jak, Actually we have developed that L3 NVE on our NE40E router products according to Virtual Subnet (http://tools.ietf.org/html/draft-xu-virtual-subnet-08) and we are still improving it based on the experiment results. At present, we use ARP to notify the VM attachment event so that the L3VPN PE upon receiving that gratuitous ARP packet from the moved VM could update the corresponding host route in the associated VRF and advertise that host route to remote PE routers accordingly.
If you need more detailed information on that, please feel free to contact me.
