*NIX: Relatively Minimal Host OS for VirtualBox Use

Didn't know there was some kind of ARM support for Xen.  Sounds neat!

Put forth some effort regarding Qubes.

No real success at booting -- tried on two notebooks.  Also tried their alpha Live USB media.

Might try on a desktop at some point.

Edvard:
@Deozaan: I've found that in many cases, Wine runs Windows games better than Virtualbox.  With Wine, at least you have access to the GPU (not perfect all the time, but it's mostly there).  I can run Trackmania Nations Forever at good-to-acceptable frame rates, where doing the same on a VirtualBox instance of XP was just short of painful.  If that's all you're looking for, give it a go, but for most mundane 'This-is-a-job-for-Windows' tasks, VirtualBox has served me just fine.  I've also tried Qemu, and it works quite well, but you really have to be a bit of a wizard with the command-line options to get the best performance out of it.

Deozaan:
My understanding is that it would be like running Windows in a VirtualBox VM (or any VM), where the guest OS doesn't get direct access to the GPU so many video-intensive things would be slow or non-functional. Especially programs which try to grab fullscreen access [such as games].

I have some new (to me) evidence to suggest that using Windows as a guest OS actually is feasible, with near-native performance.

Here's a post from Sep 2012: HOW-TO make dual-boot obsolete using XEN VGA passthrough
Here's one from Dec 2015: HOW-TO make dual-boot obsolete using kvm VGA passthrough

So I may be looking into this topic again soon(ish). :)
