hi,
I am thinking if it is possible to port KVM to Mac OS (leopard). Is
there anybody doing this already?
I've considered doing it, but haven't gotten around to it, due to
lack of
inspiration.
The biggest problem IMHO is the sync. Rewriting a kvm module for
Mac OS X
should be fairly easy, but you'll miss all the good bugfixes from
upstream.
Using the upstream code with a wrapper on the other hand is
probably a
really big hassle, because osx doesn't really know about mmu
notifiers and a
lot of other Linux internal things.
Most of the special Linux internal things are optional when using the
external kernel modules (in order to support older host kernels).
If you
rely on that, there shouldn't be a huge amount of Linux-specific
dependencies.
Best thing to do would be to avoid touching the KVM source code as
much as
humanly possible, and try to write a compatibility layer on top of
the
external kernel modules. You could even use awk trickery like make
sync
does. That way you can get bugfixes almost for free.
Thanks! I am reviewing the possible interface wrapper solution now.
But I just notice that the current leopard is 32-bit. Will this be a
problem to run KVM as it always assume qemu-x86-64 bit?
The Linux kernel module does work on 32 bit systems too. But please
keep everything 64-bit aware, as the 10.6 kernel will be available in
x86_64 flavors.

So if you come up with a good idea for this problem, I'd be glad
to help
you out as much as time permits :-).

If it is possible, which KVM release should I use as a start?
Thanks,
Neo
