Hi,

I'm using 3 node scenario for openstack KILO for my setup. After launching VM, it is not getting IP from DHCP, every time I see in the console-log of VM.

Starting network...
udhcpc (v1.20.1) started
Sending discover...
Sending discover...
Sending discover...
Usage: /sbin/cirros-dhcpc <up|down>
No lease, failing
WARN: /etc/rc3.d/S40-network failed

I checked port-show for the connected port to VM in neutron, it is also DOWN.

This is how I created networks.

neutron net-create ext-net --router:external \
  --provider:physical_network external --provider:network_type flat

neutron subnet-create ext-net 200.1.0.0/24 --name ext-subnet \
  --allocation-pool start=200.1.0.101,end=200.1.0.200 \
  --disable-dhcp --gateway 200.1.0.1

neutron subnet-create demo-net 199.166.1.0/24 \
  --name demo-subnet --dns-nameserver 8.8.4.4 --gateway 199.166.1.1

Output of nova-list

root@controller:/home/user# nova list

Any Idea..??
