Oh poop. Did not think of that. Thank you!
You are welcome!
It is an OLD Windows 7 machine. There
would be no support for virtualization. The
customer's application is a 24/7 app anyway, so he
would never be able to dual boot.
If the app is 24x7, a VM may not be the best option; the VM has its
own OS and app failure modes, and now you have added any failure modes
of the VM software as well as the failure modes of the hosting OS.
Really depends on if "24/7" means "24/7 with zero downtime" or if it
means "24/7 with occasional downtime tolerated". OTOH, you *can*
build fairly resilient solutions using VMs on an underlying cluster
(see cloud providers). Depends on the specific of your situation.
