Right now the instances are failing to dhcp. I'm using nova-network with the flatdhcpmanager. I've configured a ip helper-address on the instance vlan that forwards dhcp requests to nova-network [1]. With dhcpdump I see the dhcpdiscover is making it to the nova-network node, but dnsmasq is not responding to the request [2]. When the instance is on the same vlan as nova-network, dnsmasq responds[3].<div>
<br></div><div>Anybody have ideas of what might be going wrong? My current thought is that maybe dnsmasq requires some additional option to respond to a request originating from a different subnet. Here are dnsmasq processes running, the networks I created and network configuration [4]. </div>
