Hi Jay,

I would recommend for such issues, you are welcome to open up a question on
launchpad answers - https://answers.launchpad.net/quantum
That way it will easier for folks to track the history of the issue.

Rest of the comments inline.

This is DHCP Client on the Guest VM, '--quantum_use_dhcp' just allows for
existing nova-network  DHCP service to plugged into the virtual Quantum
network.
If you are using a VM image where IP injection isn't working and the VM has
a DHCP Client configured, you will see the DHCP Client send out DHCP
discovers

I believe you are using meta-data service, a copy of your nova.conf on
OpenStack Controller, nova-network node and nova-compute node would be
helpful.

I referenced the reason for this above.

I believe, if you statically configure IP on the instance which didn't
receive IP, you should be able to test pings, but thats
a guess based on what I can make out from your email.
