Except when it isn't.

I.e. all those extra bits that are documented in the CG.

I did a bit of work on a number of Distributions and have had to 
document those little idiosyncrasies there.

You cannot assign a 'Physical Disk Device' (i.e. one that is being used 
by the Host OS) directly to a VM as the same Disk Device (at least in 
Virtual Box), but you can share a folder(s) on that Disk as Federico 
says - in my case I share a folder from my Linux Host to a Windows VM.

The 'folder sharing' feature in Virtual Box is much nicer than the other 
Virtualization platforms I think and the Windows VM sharing a Linux Host 
Directory is easier than the other way round frankly. less complicated 
to set up, but the Help that comes with Virtual box explains this.
