I have used the VMWare Converter to convert a physical XP machine into a VM so it can be used on a Windows 7 host. I have VirtualBox installed and am planning on using that as my hypervisor but am having some issues. When I try to boot the XP VM the machine freezes at before Windows loads and when I try with the i/O APIC on it has a BSOD about the HDD or HDD adapter having been changed. I have been able to get this to work with other machines in the past but am having no luck on this one. Any ideas on what to try?
