Anecdotally, after a recent upgrade of BIOS on my laptop, for about a week it did not support 64-bit VM guests despite Virtualization support marked enabled in BIOS. I tried all sorts of things, until I found that for the past few years (and many releases) this well known vendor has a typo, and this choice is inverted. But by the end of knocking on walls with my head, I was morally prepared to continue using the existing Hipster guest installation as a 32-bit one, and happy that I could seamlessly do so.
