Think "cloud providers"

Today, you can grab a physical NIC and create some number of virtual NICs. Same for GPUs.

I guess the idea is that you have some hardware, and each kernel (read "virtual machine") will get:

  - some dedicated CPU
  - some physical memory
  - some virtual NICs
  - some storage, maybe (if dedicated; if through network, then nothing to do here)
  - maybe a virtual GPU for the AI hype train

Every kernel will mostly think it owns real hardware, while in fact it only deals with part of it (all of this due to virtualized hardware support that can be found in many places)

This feature does not seem like a general-usage feature, which can be used in our laptop
