Thanks for posting this, Patrick. I understood "physical devices" as "host
server" not as "bare-metal server".

I suspect we could use the same agent framework, but almost all of the
pollsters would need to be different because they would be running inside
the guest OS rather than on a host VM, so the APIs they will use to collect
the same data will be different.
