<div>Hi,</div>
<div> </div>
<div>I have installed grizzly with quantum and ovs-plugin. It seems that grizzly allocates the third address of each subnet for dhcp. (In folsom it was the second address). This means that the VMs will get addresses .2, .4, .5, …</div>
<div> </div>
<div>In my setup the first VM always boots fine and gets the address x.x.x.2. This can be seen in the syslog:</div>
<div> </div>

<div> </div>
<div>The problem comes when I start the second VM. Nova shows that the x.x.x.4 is allocated</div>

<div>But from syslog I see that the answer to the DHCPDISCOVER is “no address available”</div>

<div> </div>
<div>When I restart the quantum-dhcp-server the problem disappears. This can be seen from the syslog:</div>

<div>What could be the problem? Have you seen similar behavior? If yes, how did you fix this?</div>
