I've been looking unsuccessfully for documentation on this option...so<br>
I'm not sure exactly what it does.  However, if I understand<br>
<a href="https://bugs.launchpad.net/nova/+bug/953712" target="_blank">https://bugs.launchpad.net/nova/+bug/953712</a> correctly, it requires the<br>
dhcp_release command, which is sometimes part of the dnsmasq package.<br>
I'm running on CentOS 6.2 and dhcp_release does not appear to exist.<br>
<br>
On the other hand, simple database manipulation seems to resolve the<br>
problem, so would everything work just fine if I added a no-op<br>
dhcp_release command?<br>
<br>
I'll give this a shot later tonight.<br>
