Virtual machines from .vdi images

I wasn't trying to side-step the issue. The Intel-based system that I
tried this on just doesn't have Linux installed (it's a Windows machine)
and I only moved over the hard drive with the Genode build on it to attempt
the boot. At some point I will need to run Linux on that machine but I had
other more pressing goals from my boss (specifically to find out if USB can
be used) to try to get through before getting Linux on and checking this.
Something that may be of interest, however, is when I have been sifting
through the Linux AHCI driver source code
https://github.com/torvalds/linux/blob/master/drivers/ata/ahci.c I found a
comment in the code regarding the AMD controllers at line 409:
/* AMD is using RAID class only for ahci controllers */
This may have something to do with the Genode AHCI driver not working on
AMD controllers and might help lead in the right direction for a resolution.
