[ale] snarky use of RedHat - heh, heh

Tue Oct 30 09:34:10 EDT 2012

What Scott's referring to is RHEV compute nodes are available in thick 
or thin hypervisor models somewhat like the ESX vs ESXi hypervisor 
distinction in VMware

- you can take a standard RHEL box, make sure it has the appropriate 
KVM, libvirt, etc RPMs installed, and point it at your RHEV manager. 
That has one licensing model, but gives you compute nodes that are full 
standard Linux servers with all the accompanying pluses and minuses

- you can deploy RHEV-H which is a very stripped down embeddable install 
-- essentially just a Linux kernel, KVM userspace tools, and the glue 
needed to make it go and communicate with the manager. It's licensed 
slightly differently, but gives you streamlined dedicated compute nodes 
with reduced attack surfaces, etc that can potentially be run from flash

You can mix and match the two hypervisor types as needed under the 
control of the same manager
