After deployed DevStack, I managed to create cirros instances. Now I want create CentOS instance:

1. I download image CentOS-7-x86_64-GenericCloud-1608.qcow2 from [here].(http://cloud.centos.org/centos/7/images/)
2. Then I run nova boot --flavor 75c84ea2-d5b0-4d99-b935-08f654122aa3 --image 997f51bd-1ee2-4cdb-baea-6cef766bf191 --security-groups 207880e9-165f-4295-adfd-1f91ac96aaaa --nic net-id=26c05c99-b82d-403f-a988-fc07d3972b6b centos-1
3. Then I run nova list, it gives: b9f97618-085b-4d2b-bc94-34f3b953e2ee | centos-1 | ERROR | - | NOSTATE

4. It is in ERROR state, so I grep log with that b9f97618-085b-4d2b-bc94-34f3b953e2ee (instance id): grep b9f97618-085b-4d2b-bc94-34f3b953e2ee *.log

5. The grep returns:
