<p class="MsoNormal" style="margin-bottom:12.0pt">Problem is My VM does not get the IP from the DHCP pool configured. Though at dashboard, IP is shown but on VM console It is not visible.Hence I am not able to ping the VMs. If I manually add the same IP to
the VMs and add flow entry to br-int, then only I am to ping.<u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Can anyone please help me out here, as why IP is not getting assigned to VM and on manully adding IP, controller is not coming into picture.<u></u><u></u></p>
