I just installed Windows 8 on my computer. I got the ISO and the product key from my university so the software itself is sound.

I use alot of virtual box. And ever since I moved to Windows 8, I have noticed that virtual box crashes more often. In particular, it is very very bad at opening multiple guests. My CPU usage will be at like 20% and I only have 3 guests open and my entire computer just freezes. Cursor and all. In Windows 7, I was able to open like 6 (not that I ever needed to) and really push my CPU.

I havent experience any other issues with Windows 8 yet.

Has anyone encountered this?

Thanks!

Note that Windows 8 Pro has Hyper-V bundled with it (not installed by default) I only encountered an issue (VirtualBox VMs won't even boot up) after installing Hyper-V. You can always switch to Hyper-V (or at least try it, like I'm doing now) instead of VirtualBox –  Shady M. Najib Nov 18 '12 at 8:12

Ask it in the official Virtualbox forum or create a ticket in tracker.

VirtualBox crashes very often in Windows 7 and Windows 8 on my i3 with Radeon laptop. You could either try Hyper-V (if you're using Windows 8 Pro, and your hardware supports it), or try VMWare Player
