All services seems to run fine. When tried to launch instance I see<br>
below errors in nova-conductor logs and instance stuck in "scheduling"<br>
state forever.<br>
I dont have any config related to n-cell in controller. Could someone<br>
help me to identify why nova-conductor is complaining about cells.<br>

I don't see anything above that is complaining about "No cell mapping found for cell0"? Perhaps you pasted the wrong snippet from the logs.<br>
<br>
Regardless, I think you simply need to run nova-manage cell_v2 simple_cell_setup. This is a required step in Ocata deployments. You can read about this here:<br>
