mechanism but the fact that the installed kernel and drivers depend on the
actual hardware.

The problem lies with Windows, in that its driver settings, particularly
for storage devices, are not portable. Unless you modify the Windows
registry to force start storage drivers for both the physical and virtual
machines, you will mostly likely end up with a ``0x0000007B`` STOP blue
screen error each time which will require a restore or modifying the
registry to fix.

It's even possible to transfer a Linux install to a USB enclosure
and boot it directly on another machine of the same architecture,
although the kernel will lack proprietary drivers (e.g. some wifi cards).
