Hi,
I have recently finished installing a minimal OpenStack Queens
environment for a school project, and was asked whether it is possible
to deploy an additional compute node on bare metal, aka without an
underlying operating system, in order to eliminate the operating system
overhead and thus to maximize performance.
Whomever asked you about this must be confusing a *hypervisor* with an
operating system. Using baremetal means you eliminate the overhead of
the *hypervisor* (virtualization). It doesn't mean you eliminate the
operating system. You can't do much of anything with a baremetal machine
that has no operating system on it.
Best,
