I had working setup with Havana and nova-network with multinode setup. I was able to create the instance and login etc. I wanted to try Neutron with following setup.

  1. Host1 - Controller, Compute, Neutron Server, Ovsplugin. This system had nova-network. I have stopped that service.
  2. Host2 - Compute
  3. Host3 - Neutron dhcp-agent.

When I create the instance it always stays in 'scheduling'.

Troubleshooting done:

  1. No errors observed in /var/log/nova*.log - Checked on controller
  2. No errors observed in /var/log/neutron/*.log - Checked on controller
  3. No errors observed in /var/log/neutron/dhcp*.log - Checked on host3 which has only dhcp agent.
  4. /var/log/libvirt/qemu/ does not have instance
  5. /var/lib/nova/instances does not instance entry
  6. If run 'nova console-log <id>', it displays the error saying instance is not ready.</id>
  7. I have shutdown the nova-network on the controller.
  8. /var/log/syslog does not have any error
  9. dmesg command on ubuntu does not display any error.

I dont' see any errors anywhere. Any inputs on how to troubleshoot this ? Without any logs it is becoming difficult to troubleshoot.

Can you provide output of nova-manage service-list ?

I did troubleshooting this myself. I have compiled my experiences in the following link. I changed the value in nova-compute.conf to qemu. It started working fine. This looks simple. But it took 2 days to figure out based on deep troubleshooting.
