Open Stack

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.

Thanks to all who responded.

Regards,
Ahmed.
