Hi,<br>
<br>
I had the same problem.<br>
My problem was that the openvswitch plugin's config file was missing
on the controller node, and because of this, the horizon used
"local" network not "gre" (the same problem can be the problem with
VLAN setups)<br>
<br>
you can chek it with neutron net-show.<br>
<br>
I hope it helps<br>
<br>

<div style="font-family: 'lucida Grande', Verdana; line-height:

on both network and compute node, it says the dhcp request
successfully leaves compute node, and it can reach the
"int-br-eth1" of network node, but not the next step br
"br-int", so the dnsmasq would not able to ack. I think this
is the problem why I can't get dhcp ipaddr.</span></div>
