Hello,
I have a two node cluster running on Ubuntu 11.04 (natty) with the Diablo release from ppa:openstack- release/ 2011.3
[2011.3 (2011.3-nova-milestone-tarball:tarmac-20110922115702-k9nkvxqzhj130av2)]

Controller node  runs nova-compute, nova-volume, nova-network, nova-api - 2 NICs
Compute node runs nova-compute, nova-network and nova_api - 2 NICs
 
I am using flatDHCPManager.

When I launch on instance on the compute node, the VM is getting ip from the company dhcp server. It is not getting IP from the dnsmasq-dhcp server.
Also, I do not see dnsmasq-dhcp up on the compute node.

In the console log, I see that 
 
Sending discover...
Sending select for 16.89.26.95...
Lease of 16.89.26.95 obtained, lease time 1296000
starting DHCP forEthernet interface eth0  [  OK  ]
cloud-setup: checking http://169.254.169.254/2009-04-04/meta-data/instance-id
wget: can't connect to remote host (169.254.169.254): No route to host
cloud-setup: failed 1/30: up 2.04. request failed
wget: can't connect to remote host (169.254.169.254): No route to host
cloud-setup: failed 2/30: up 6.05. request failed

How to bring up dnsmasq-dhcp on the compute node?
 
Any help is appreciated.
 
Thanks,
-Jay
