Configuration: OpenStack Networking, OpenvSwitch Plugin, OpenStack Networking Security Groups
Release: Grizzly

Sometime when creating instances, the dnsmasq instance associated with the tenant l2 network does not have configuration for the requesting mac address:

Jun 11 09:30:23 d7m88-cofgod dnsmasq-dhcp[10083]: DHCPDISCOVER(tap98031044-d8) fa:16:3e:da:41:45 no address available
Jun 11 09:30:33 d7m88-cofgod dnsmasq-dhcp[10083]: DHCPDISCOVER(tap98031044-d8) fa:16:3e:da:41:45 no address available

Restarting the quantum-dhcp-agent resolved the issue:

Jun 11 09:30:41 d7m88-cofgod dnsmasq-dhcp[11060]: DHCPDISCOVER(tap98031044-d8) fa:16:3e:da:41:45
Jun 11 09:30:41 d7m88-cofgod dnsmasq-dhcp[11060]: DHCPOFFER(tap98031044-d8) 10.5.0.2 fa:16:3e:da:41:45

The IP address (10.5.0.2) was re-cycled from an instance that was destroyed just prior to creation of this one.
