After the success deploy, I try to create a instance and launch it.
But it failed.
The error is :
Message Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance b238edf6-093b-41ce-bd59-a349f8e8fa12.

Why ?
For the answer to that question you have to check the logs of nova-scheduler and possibly also nova-compute. -yoctozepto
