[Qemu-devel] [bug] qemu-0.10.4 crash trying to add new disk under Win2k guest

[Sergei Steshenko]

Hello,

I've tried to run QEMU using the following command:


(export QEMU_AUDIO_DRV=alsa;export QEMU_ALSA_DAC_BUFFER_SIZE=16384;export QEMU_ALSA_DAC_DEV=hw:0;/mnt/sdb8/sergei/AFSWD_debug/install/qemu-0.10.4/binsh/qemu -m 256 -hda win2k.img -hdb /mnt/sda5/sergei/QEMU/drive_D.img -localtime -kernel-kqemu -tftp `pwd` -usb -usbdevice tablet -soundhw sb16) &
.


'/mnt/sda5/sergei/QEMU/drive_D.img' a freshly created image, the command
line was:

/mnt/sdb8/sergei/AFSWD_debug/install/qemu-0.10.4/binsh/qemu-img create drive_D.img 8G
.

When in Win2k I tried to access the disk (Control Panel ->
Administrative Tools -> Computer Management -> Disk Management) clicking
on the Disk 1, QEMU crahed withe following output on console:

EAX=000000c8 EBX=00000100 ECX=00000000 EDX=e1ce63c8

Unsupported return value: 0xffffffff
.

The crash does _not_ happen with qemu-0.9.1, but -kernel-kqemu is not used
with qemu-0.9.1.

So, it's either a regression or a kqemu problem.

Thanks,
  Sergei.

Can you reproduce without -kernel-kqemu?
