The iommu=soft enables in the kernel the Software IOMMU. This is
required for PCI passthrough devices. But the problem isn't with those
flags (I've asked the user to extract the kernel and initrd and use
those exact parameters and just do a PV boot - and it worked).

The problem is that MiniOS is doing something wrongly.. I don't know if
the problem is with arguments or if the underlaying storage is the issue
(tap:aio) with MiniOS.

Heheh. Yeah figured but in case you have a todo list thought this might
be a good thing to put there.
