> It will still be possible to start up an x86-32 operating system inside a VM – these have to emulate system firmware in any case, alongside the emulated graphics cards, network cards and so on that they must provide.
> You will also still be able to run x86-32 binaries and apps in ring three on your 64-bit OS in ring zero – so long as the operating system provides the appropriate libraries and APIs, of course.
