This MAC belongs to Dell.

Do you have a problem with DHCP or Centos? Your Neutron agents are OK, you dump a lot of config information, and you run upgrade-heads, which you should not do on a populated DB. A Dell machine wants an IP address.

Centos doesn't start. Where is it hanging? What is its status? Console log?

Hi Bernd, thanks for the response. I used new ubuntu working vm in another platform, as soon as i launch VM status changed to Error. No valid host. i have added /nova-conductor.log above where i see error

please check and guide me . Thanks

No valid host was found means that the scheduler didn’t find a compute host that matched the description of the instance. Debug logs in the scheduler should tell you what the problem is, or the placement log.
