Exceeded maximum number of retries. Exhausted all hosts available for retrying

[jay]

after installed openstack, I used the following command to create an instance, but it's failed.
# openstack network list
# openstack security group list
# openstack server create --flavor m1.nano --image cirros-0.5.1-x86_64-disk --nic net-id=xxx --security-group xxx instance_name

It shows the following errors:
```
Traceback (most recent call last): File "/opt/stack/nova/nova/conductor/manager.py", line 669, in build_instances raise exception.MaxRetriesExceeded(reason=msg) nova.exception.MaxRetriesExceeded: Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 122d7907-a8c9-49ec-b55c-066e18eb20a4.

It hint me an error on the dashboard:
```
Invalid service catalog: identity Details
Invalid service catalog: identity
```

You would have to check for errors in the logs for the various Nova services, e.g. "journalctl -u devstack@n-cpu"

This looks o.k., is there some error later? Please also share your local.conf file.

In my case I was using another projects security group, which resulted in this error
