I think, I have problem with DHCP . The compute node doesn't bring ip from dnsmasq-dhcp(from nova-network).

console.log tells me that

I have a two node cluster running on Ubuntu 10.04.3 with the Diablo release from ppa:openstack-release/2011.3

Each machine has two NICs, but two NICs is on same network.

I use flatDHCPManager.

Following are the config files of both nodes. This is the cloud controller(nova-api, nova-network, nova-scheduler) configuration. http://pastebin.com/UVBtmvGc

This is the compute node. http://pastebin.com/j582m5rU

Following are network configurations. This is the cloud controllers. http://pastebin.com/w0i42NYP

This is the compute nodes. http://pastebin.com/Tuu8G3zY

Answer plz.
