Does the openstack server stop command do an ACPI shutdown or does it do the equivalent of pulling the power plug?

I want to know if it’s safe to run this command rather than logging into the machine and running shutdown (for say a RHEL7 instance).

If it does an ACPI shutdown, what happens if the machine doesn’t respond? Is there a command to force the machine off?

The client-side command doesn't have any say in that. On the server side, it depends. There is an image property "os_shutdown_timeout" which can override the server-side configured graceful shutdown timeout - which defaults to 60 seconds. So if you want to control that timeout in your images you can use the image property. See [1] for details.
