See above: the radios and antennae I can get as add-ons for a Xeon-D 1U pizza

hardware like an U6-LR can do in terms of cost and performance.
Um... you can't "virtualize" WiFi in any VM I've ever seen.
You can though pass PCIe devices to a VM. The hardware will physically
attach to the control host, but a VM will be able to do anything it wants
with it.
So the guest has the potential to crash or hang the host?
Passthrough devices aren't really handled by the host OS (it's commonly
required to blacklist their kernel drivers to make sure the host does
NOT touch them) so in most cases if something hard-crashes and a kernel
panics it's still all drama that happens inside the VM. This is how it
usually goes in my experience.
GPU passthrough can cause a whole host to lock up and require power
cycle. I've seen that happen in the wild only once (it was repeatable,
fun times), but imho it's a IOMMU or GPU issue not a "normal" thing that
should happen.
