We run everything on VM just for flexibility. Want to stand up a new machine for testing? Boom, run the script, new Ubuntu server. We need to decommission a machine. Shutdown all the guests, move them over to new machine and start them.

Sure, most of what we do is very cattle and we could run on bare hardware but why not take advantage of easy to add flexibility.

I'm not sure I follow. Ideally your bare metal machines have an easy bare OS with some config that is easy to repave, and are ephemeral-ish (not a lot of state).

Your "machine for testing" would be a container. Decommissioning a container is easy. Decommissioning a physical machine only happens when it's obsolete.

sigh Not everything in the world is containers. Applications running outside of container still exist in many companies for various reasons including political ones.

Yeah this - I know my container is pushing a lot of things to containers (I think customer-facing web stuff is a reasonable use for containers) but stuff like ActiveDirectory controllers, Exchange servers - pretty much any Microsoft thing running on Windows - will continue to run on a VM for the forseable future.

Okay, but that's not at all what this thread is about? We're talking about having a VM intermediary between containers and bare metal. Not applicable to cases where you don't have containers because your workloads aren't fit for them.
