Silly question, btw -- I've heard on several occasions that kqemu is not auditable. Is it even possible to produce a replacement with reasonable performance that *is* auditable?
Is it possible to produce a large scale system-level program (esp. with smp) that is auditable? I think not.
kqemu is particularly difficult because it interacts with the hardware in complex ways.
(Whilst I certainly have the interest, I'm not sure whether I possess a sufficient quantity of the other four required attributes to implement something like this for KVM, if such a thing is even possible.)
It's technically possible, but I don't think it's realistic. No one wants to code for yesterday's hardware; every day there are fewer machines that need kqemu.
If you're interested in virtualization, but a cpu that supports virtualization. If you want to keep your old cpu, keep your old software as well.
-- Do not meddle in the internals of kernels, for they are subtle and quick to panic.
