I once wanted to text Windows 7 XP Mode on my notebook or my home PC but unfortunately I failed as both CPUs do not support Hardware Assisted Virtualization (HAV).

Now, we released an update for Windows 7 64bit systems to remove this requirement: Update for Windows 7 for x64-based Systems (KB977206). This could definitely help with migration.

BTW: You need a genuine version of Windows ;-)
