Fun fact: You can still run 32-bit VMs on a system even if Intel VT-x and AMD-v are not enabled in the BIOS. Had an odd situation where running a VM helped me get around a bunch (like 5) of endpoint security products.

Yes! I discovered this a few years ago when someone told me it was impossible to virtualize VMWare on top of Hyper-V. It is indeed possible, but because of the limitations mentioned above (no passthrough) only 32-bit VMs will run.

Don’t ask me why I was attempting to run VMWare virtualized atop Hyper-V. Uh, it was for…stuff.
