Thanks Jay for the response. Sorry I missed out on copying right error. Here is the log: 2017-02-20 14:24:06.211 TRACE nova.conductor.manager NoValidHost: No valid host was found. There are not enough hosts available. 2017-02-20 14:24:06.211 TRACE nova.conductor.manager 2017-02-20 14:24:06.211 TRACE nova.conductor.manager 2017-02-20 14:24:06.217 ERROR nova.conductor.manager [req-e17fda8d-0d53-4735-922e-dd635d2ab7c0 admin admin] No cell mapping found for cell0 while trying to record scheduling failure. Setup is incomplete.
I tried command you mentioned, still I see same error on conductor. As part of stack.sh on controller I see below command was executed related to "cell". Isn't it devstack should take care of this part during initial bringup or am I missing any parameters in localrc for same?.
