16-bit x86 code dependent on interacting with real hardware under precise timing doesn't always work well in a VM.

This reminds me of the 8088mph demo - 1k colours in CGA, and a bunch of other impressive stuff.

true, but the question was about "my currently running system (anno 2016)" - which means intel core most likely. And at that generation, there requirements for precise timing is extremely rare, it's mostly PCI/PCIe devices and they can be shared with VMs just fine.
