Christoph, this isn't a totally fucked up hypervisor. It's not even
about the hypervisor itself, I mean seriously, man, can you at least
bother reading what I described is going on with the security
architecture ?

Anyway, Michael is onto what could possibly be an alternative approach,
by having us tell qemu to flip to iommu mode at secure VM boot time.
Let's see where that leads.

Cheers,
Ben.
