Open Stack

Nope the controller does not care where it runs. AZ allows you to select the dest and its’ pretty nice since you can have a sever with SSD or VMware etc…

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.
