I have 4 computers in my modest lab. 2 servers have CPU virtualization extensions, Vx-T and 2 do not. I want to use the two NON-Vx-T servers for something within the stack. What OpenStack modules or components can I put on the non-Vx-T servers that don't require Vx-T. Any module needing KVM or LXC would be ruled out. Those modules would go to the 2 servers with-Vx-T.

except nova compute, you can run all the services on non vx-t hosts..

You can host all of the api services on the machine and you can also host the back end db's and amqp services. Also you can use qemu on the machines but it will be slow as funk.

Use the servers with VT-x for compute. Use one of the non vt-x for controller. If you need more compute, follow the recommendation in the previous answer (use QEMU on the non-vt-x server). If not I would suggest use the fourth server (the non-vt-x server) as central storage.

Just to reiterate what was said in the previous answer, you can run all OpenStack modules independent of CPU extensions.
