Re: kvm86 kernel option

I was looking at the code that allows an application to run in
'viritual 8086 mode', not anything that might allow a 'normal'
application to make bios calls - although that couls have it's
own security risks.
Okay, misunderstood your suggestion :)
I can only think of one obstacle before doing that then: real mode
support under VMs.
I do not know how much support is required from dom0 nowadays,
especially with Intel's hardware virtualization (which does not support
running VMs in real mode "easily").
IIRC, Xen introduced a real mode emulator around Xen 3.2 so they can
support a wider range of guest HVMs. I doubt that it has to rely on
v8086 mode from dom0, but this should be checked anyway.
