[Qemu-discuss] qemu for windows and kvm

[Sylvain]

 Hi all,

I had a good experiment a few years ago
with qemu-0.9.1 for windows
I recently decided to update to the latest version which
is 1.3.1 .

On my windows vista laptop
 (AMD athlon 64 dual core if it can help), I was able to run successfully
the sample bat file linux-0.2.bat .

I adapted my old .bat script
for my application. It worked but very slowly.
I decided to activate the kvm acceleration.
It failed with the message:

KVM not supported for this target
No accelerator found!

Here is the content of the .bat file :

REM Start qemu on windows.
REM net start kqemu
REM @ECHO OFF
SET SDL_VIDEODRIVER=directx
SET SDL_AUDIODRIVER=sdl
SET QEMU_AUDIO_DRV=dsound
SET QEMU_AUDIO_LOG_TO_MONITOR=1

START qemu-system-x86_64w.exe -L Bios -k en-us -vga std -m 512M -sdl 
-soundhw es1370 ^
-boot menu=off,order=dca ^
-rtc base=localtime,clock=host ^
-name RACD -drive file=linux-0.2.img,media=disk,cache=writeback ^
-net nic,model=ne2k_pci -net user -enable-kvm ^
-machine pc,accel=kvm,kernel_irqchip=on -cpu pentium ^
-cdrom 1.2.4.iso

(I obtained similar results using qemu-system-i386w.exe instead of 
qemu-system-x86_64w.exe )

In the past, it was necessary to install kqemu for windows
(the three commented lines at the beginning of the script  are a sequel 
of that; the behavior
is not changed if these lines are uncommented)

Is it necessary to update kqemu for windows ?
(the old one which was working properly with qemu-0.9.x is still there)
Or is the problem elsewhere ?

Many thanks,

Sylvain
