AROS runs in most virtualisers, although qemu+virtualiser accelerator or virtualbox have the best support (networking + sound). It also works in virtual pc and vmware, the latter of which even had gfx driver support besides vesa modes (which unfortunately has been broken for a while. No sure if they broke because of aros advancements or things changing under the hood of vmware itself(vmware gfx drivers I mean, not vesa)).
While it works fine, I personally would only opt that that route if it's someones only option, or if they're unwilling to, or not interested enough to use it natively. It's a considerably slicker experience running natively on a machine with full support and a little more stable. Still works decently though.
