Something wrong with your nova-compute:

nova-compute oscloud1204 nova enabled XXX 2012-05-17 13:05:14

So when you run an instance by: # nova boot --flavor 1 --image b5145242-4904-4521-b0b0-4065bec67a24 --key_name key1 superfrobnicator
It's return:

| OS-EXT-SRV-ATTR:host | None |
| OS-EXT-SRV-ATTR:hypervisor_hostname | None |

You must recheck nova-compute. Try to restart this service!

I have checked all the things in nova compute and again my instance is not active, many times i restart the nova-compute servive. Please suggest me the where i am doing the wrong thing.

To configure the nova-compute i followed the link http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin.

here the state of nova-compute is XXX

why nova-compute is stopped here when i start this service earlier?
