why can't I actually run both Linux and Windows and OSX all at once without some bad virtualization container inside one overarching OS? Like, can't Intel manage that with chipset and CPU logic? Sounds like what you want is a LPAR or proper type 1 hypervisor, which despite everyone claiming to be type 1 none of them really are. And this is largely caused by the various device HW standards on the PC not natively supporting virtualization (or like nvidia charging extra for SRIOV functionality on their GPUs). So what happens is that all these hypervisors need something like VirtIo or hypervisor emulation of devices (ex e1000/ne2000, sb16, etc) to provide generic storage/networking/display/input devices on top of devices which don't themselves provide any virtualization support. Which in PC land is pretty much everything that doesn't support SRIOV. Which in turn means that a heavyweight OS +driver stack is required to manage the HW. So, you could build a PC based LPAR hypervisor. It would just be limited to the SRIOV capable devices, or plugging in piles of adapters, each one uniquely bound to a single partition.
