If I remember right (and I may not), one of the problems with Plex86 v1 was the
difficulty of catching all possible transistions, from areas where it was safe
to let the code run, to areas that had to be carefully monitored.
It sounds like your idea of letting qemu handle the ring 0 stuff is going to
have the same kind of problems.
But, I could be wrong. I'm not that good of a programmer, and I certainly am
not familiar with emulator programming.

Right. And that's still very limited.
There has been a lot of excitement in the mailing list, but few have bothered
to mention that for most users, the kqemu stuff doesn't matter. I suspect most
of those people either got distracted by the license, or just kept their mouth
shut.

I'm not that good of a programmer. I have never made any comments to suggest
that I was.

1) I don't need a reason to not complain.
2) I don't need to *justify* not complaing.
3) The question is a little insulting.
But, to answer it anyway...
Fabrice mentioned long ago that his module would only work with Linux hosts. I
don't know why. Whether its his familiarity with Linux, or if it's something
that can only be done under Linux and not Windows. (I have no idea how vmware
& virtualPC do their stuff, or what method kqemu uses.)
So when he did finally release it, it was no surprise. I was already resigned
to the fact that it wasn't going to help me in the slightest. And therefor I
don't care what license it is released under. If it ever works under Windows,
then I'll care.
When you announced your plans, I was hoping that it might be something that I
and 95% of the rest of the world could actually use. You weren't clear in your
original message, so I asked.
Turns out I was wrong though.
Since it's not going to help us, I have no further interest in your project.
Your project sounds like it falls into the exact same category as qemu-fast and
now kqemu... Mildly worth knowing they exist, but of no practical value for me.
No reason to get excited or upset.
