[Openstack] [Netstack] nova+quantum vm does bind ip

Ok, that helps.  Thanks
Now, I can tell that my issue is totally different one. For me, the dhcp
query is not sent by the Linux running by the VM. It is the ipxe in the
vm sending the query. And my VM was not really boot up at all. It can
not find a valid bootable device, I will need to find a way to fix up
the image first.
thx
