Nice you figured out. Check the switch vlan tagging configuration. You need to use the trunk mode in your switch. <div>Regards, </div><div>Razique<span></span><br><div>Le vendredi 30 novembre 2012, Ahmed Al-Mehdi a écrit :<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I resolved this issue. The problem was the switch was dropping the DHCP request packet sent by the VM. I verified using "tcpdump" that the packet was going out the physical ethernet port of the compute node. However, the packet did not show up at the ethernet port of the controller node. I verified the two ports are on the same (physical switch) VLAN. I then setup direct connect, bypassing the switch, and the VM was able to get a response to the DHCP request, etc. Time permitting I will investigate why the switch was dropping the packet.<div>
