First of all I am facing the issue with the nova-docker setup. After certain R&D can be able to fix the issue.

Thread reference: https://ask.openstack.org/en/question...

Now I am facing the Issue in launching the Instance. When I am trying to launch the container I am getting the error in instance overview of horizon as follows:

Message

While I was checking regarding this issue I can be able to see the nova scheduler log is showing the details as follows:

2016-09-02 16:08:01.384 WARNING nova.scheduler.utils [req-a4c0701d-04b4-433d-ad64-db09bed4c107 admin admin] Failed to compute_task_build_instances: No valid host was found. There are not enough hosts available.
Traceback (most recent call last):

    raise exception.NoValidHost(reason=reason)

NoValidHost: No valid host was found. There are not enough hosts available.

Update:

Now getting a error as follows: nova-conductor
