headless embedde linux

[heinz]

Hi KVM guys,

reading the kvm doku and think about real time together with windrivers 
anouncement of a real time hypervisor I had an idea.
Not sure if this is possible, but I am sure you guys will have an answer 
to that:

I can think of a box, running a minimal linux (without any display, 
serial console only -> head less ;-))

This kernel does support kvm and the prement patch to make it pretty 
good for real time things.
A kvm virtual machine is running for example windows xp with some WPF 
gui. That would be a nice solution,
and for many problems - including those windows gui guys needing real 
time as well.

I a don't touch any graphic card with the linux stuff, would it be 
possible to directly access from within the guest os?

Heinz

Thanks for being so patient

I can't comment on suitability for real-time work, but as a 
built-to-purpose embedded Linux distro that runs guests through KVM for 
remote use, you might find oVirt [http://ovirt.org/] interesting.

PCI passthrough support for video cards is a frequently asked about 
here, but every status report I've seen has been to the effect that it 
probably shouldn't be expected for a while.
