Dear List,
This small note to help users of Win4Lin trying to use QEMU with kqemu :
either mki-adapter or Win4Lin (device drivers used by Win4Lin) probably
uses major 250, hence prohibiting use of kqemu.ko. A temporary fix is to
unload them (/etc/rc.d/init.d/Win4Lin stop). After that, qemu uses kqemu
(no more "incompatible kernel" message), and works like a charm.
The real problem is win4lin uses devices 244-253. I put keqmu at 239 and
happily use both together
I have not yet done real tests, but my first impression is that the real
fix to the drivers problem is to drop Win4Lin entierely : QEMU with
kqemu seems a better solution (may even be faster, at first sight) to my
needs...
win4lin running win95->winme is much, much faster than qemu running either those, or win2k. Horses
for courses of course, but for my day to day stuff I can do on WinMe, it's just bucketloads quicker.
So kqemu is not faster by a very long way. Shame, but I'm sure it will improve
over time.
