I'd like to install openstack in a mixed environment. My environment consists of : raspberry pi 2 various x86 machines

I use the raspberry pi to monitor things and as a way to remotely wake up and shut down the x86 machines. The x86 machines run either opensuse or windows. What i would like to do is use the raspberry pi 2 as the controller and every other x86 machine as the compute/storage/network node.

I want to build a cluster which sole purpose is to use the combined hardware resource to run software. i want the software to have access to hardware (GPUs, CPUs, anything openCL capable) regardless of where it is located.

One thing that confuses me is that to use openstack you also need a hyperviser but i have the OS installed on bare metal instead of virtual. In order to make use of openstack is virtualisation required to use the combined resources of multiple machines or to run the software on the host OS instead with openstack making it look like a cluster?

For storage, is it possible to store a single instance over multiple nodes for faster access times (a bit like raid 1 but over seperate machines for the guest image).
