 nova boot --flavor 2 --image CentOS6 --security_group default CentOS

Note: All services are one server. If my IP is 10.10.1.12 which is a dhcp static address. When I create my network, do I use the same dns?

For the fixed_range_v4, do I use the same subnet ie, 10.10.1.0/24 ?

You have logs for 13:52:36.521 - 13:53:43.883, but your failure message is tagged 18:53:44. No valid host can mean that the resources you've requested are not available on any compute hosts. Check /etc/nova/nova.conf for your allocation ratios (cpu, memory). Does m1.small send you over the limit?

I got the same error message but because of a different reason. I had to chose another flavor: My scheduler.log showed FlavorDiskTooSmall: Flavor's disk is too small for requested image.

nova show … and the file scheduler.log apparently print out time differently. At least it's like that for me, I have a difference of 2 hours between them because of my time zone.

Make sure you have AMPQ Queues (qpid in your case) running and well configured in your Openstack components and the Centos Firewall opened to accept connectios to QPID Port.
