[Qemu-devel] QEmu freezes Linux while installing win98 or win2000

[Jorge]

Hi all,

first, thank you for your efforts in developing this promising program.

Mi problem is as follows:

When I try to install win98 or win2000 (the only legal versions I have), QEmu 
performs well in text mode, but when it switches to graphics mode, sooner or 
later the whole Linux box will freeze, I'll have to reboot the machine in 
order to use it.

I've tried with different kernels, the GPL'd video driver for my card 
(NVIDIA), but the result is always the same, it freezes. It doesn't freezes 
at the same position (of the win install procedure), sometimes it does it 
after 5 minutes, others after 30 minutes.

I've tried a QEmu compiled from source and the downloadable i386 binary, both 
do the same.

What could it be? That a program that is run from a "normal" user freezes the 
whole linux system?

My specs:
QEmu 0.5.4
Atlhon 1.7
512 Mbytes RAM
90 GBytes HD
Mandrake Community 10
NVidia GForce4 with NVidia drivers
KDE 3.2
Kernel 2.4.22-10mdk (Mandrake patched with supermount and other stuff)

Thank you in advance

Hi,
The last time I had bizarre problems (freezes, crashes, which finally killed 
my system by corrupting the fs) was because my ram was faulty. Since the 
faulty bits were in the >200Mb area, the bugs did not show up until I ran 
memory-hungry processes. In your case Qemu maybe with -m anawfullotofmemory? 
I realized it was my ram when I tried to build gentoo and got various 
segfaults during the build, and memtest86 confirmed this.

are you sure it is not just the X server that "freezes" because of the
mouse&keyboard grab? Try ctrl-alt-F2 or remote login.

It would mean that there is a bug in Linux (?) OR in NVidia drivers OR you ran 
qemu as root (!) OR the system is not really crashed. You probably lost the 
screen in the back...
