Qemu and HDD image

Hi,
I followed this guide
http://wiki.kolibrios.org/wiki/Setting_up_QEMU about how to run KolibriOS on Qemu.
All works ok, I can create the hda.img file and copy a file there. But the problem is that I have to boot with option
set to 'on', because KolibriOS detects the disk as /hd0/1 but doesn't show the content. With the option set to 'on', KolibriOS shows the content of the disk in /bd0/1.
What could be the reason?

Unfortunately, I can't explain the reason, but it works in qemu-1.2.2. I use this version to access my /dev/sda.

Maybe to someone is useful know the warning from Qemu when trying to access /hd0/1
Code: Select all
main-loop: WARNING: I/O thread spun for 1000 iterations

I haven't found a binary for Ubuntu of Qemu 1.2 and the compilation gives some error that was fixed in a next version.
I will see what can I do.

There are many flags to disable features. Try this:
Code: Select all
./configure --target-list=i386-softmmu --audio-drv-list=alsa,sdl --disable-vnc --disable-bluez --disable-docs
Works on my computer (c).

Thanks dunkaist! It compiled and worked as expected.
I set to off the option and hda.img is detected correctly as /hd0/1.

OpenMoon,
these instructions are for qemu-1.2.2 which is rather outdated at the moment.
For current qemu version just install it and then add usb drive via '-usb -usbdevice disk:format=raw:fat:.', example:
Code: Select all
qemu-system-i386 -soundhw hda -drive if=floppy,file=kolibri.img,format=raw -boot a -usb -usbdevice disk:format=raw:fat:. -net nic,model=ne2k_pci -net user
