That sounds right. And by the way, if you wish to pass the original
Windows installation as a physical disk to your Windows domU, you can do
that too, and it can then be used as to store files - you just don't
start the Windows installation that is on there. If you do things right,
you can probably run most applications you have on the already existing
installation too - but some applications become unhappy when you change
the environment around them, so may not work [also, apps that install
.DLL's into the Windows directory will need to have the relevant DLL's
re-installed on your Guest installatin].
