reactos in lguest

[Enrico Weigelt]

Hi folks,

did anyone already do some research on whether ReactOS could 
run in lguest ?

Maybe this could be a nice for development/debugging and 
attracting more people ;-)

I dont see it possible. lguest, even though its a hypervisor, doesnt offer
full virtualisation. It requires a Linux kernel as guest, one that supports
lguest. ReactOS is NT-based and doesnt use Linux kernel at all.

Maybe Xen or KVM would be better suited for this? Have either been tested?

KVM is not much more than QEMU using Linux kernel modules for 
hardware-assisted virtualization. It can run pretty much every x86 OS, 
and so does our Debug Buildslave use it for regress-testing ReactOS 
builds regularly.

Cheers,

Colin

Not entirely true. There's also a Plan9 port for running in lguest.
AFAIK it needs a bunch of precautions (eg. coping with the fact
that on bootup, it's already in protected mode, etc) and call 
certain vectors for privileged operations instead of doing them
directly.

Still, this calls for porting effort, for which i dont see any volounteers.

What would be benefits, bytheway? I am interested in different kernel  
architectures, so it would be useful to see how usable can be ReactOS  
ported to lguest in future, etc.

WBR,
