Can I install Nova controller and compute nodes on the same host?

I have a server running VMware ESXi. I created a VM on it which I plan to make my Nova controller node. I understand that the nova-compute service has to be running on any host that VMs are created on. If I would like to create VMs on top of ESXi which the host is running, can I do that by having nova-compute running on a VM on top of ESXi or would I have to install nova-compute directly on the server without the hypervisor?

Not always, and not in the case of VMware.

If your Nova instances are implemented by VMware VMs, nova-compute drives an ESX cluster (which consists of a single host in your case). In this case, you can run nova-compute on the controller or a different node. I doubt that ESXi can be a platform for Nova; Nova does expect a regular GNU/Linux OS.

For details, see Nova’s configuration guide.
