Upgraded (old motherboard died) to AMD AM2+ Phenom (with an Asus M2 motherboard) and got a 0x0000008E blue screen. I see a pattern here, pointing to AM2+ Phenom. This ticket http://www.virtualbox.org/ticket/1627 Looks awfully similar to my situation. But, as far as I understood, he manages to boot into the OS. I can't even do that. The exact scenario is: - When installing XP from scratch, on a new virtual HD, the first install phase (the one in Text Mode in which you choose the install partition and a first batch of file copying takes place) all goes through fine. When the system boots, for the second install phase, that one with an actual GUI, before the GUI appears the 0x0000008E happens. Interesting facts: - Microsoft's Virtual PC 2007 (with and without Service Pack 1) has the EXACT same behaviour. - VMWare Workstation works fine! And thats exactly what I found out last night and used as a workaround. I created a vmware machine using a link to the ""3rd party"" virtual hard disk. And it managed to boot fine and I had my old vm back. Sun and Microsoft need to do whatever magic VMWare does to coupe with whatever AMD Phenom is doing." defect closed VMM VirtualBox 1.6.2 worksforme AMD Phenom AM2+ BSOD other other
