Why don’t you use AZ for this. So you can select where you want to run a specific VM. Then you have VM on KVM, XEN etc.. based on the AZ.

At this point, I have all the necessary packages installed and working on everything but the compute nodes.  What I need to do is to build an KVM node and a Xen node first, then worry about VMware later.
