Question about qemu and kqemu in fedora 7


Hi there,

I get a problem with qemu in f7. The qemu is installed within f7 at beginning. And when I wanted to use it, I saw people online said that the kqemu should also be installed while using qemu. So I download the kqemu from its main site. The name of the file is "kqemu-1.3.0pre11.tar.gz".

And I follow the steps below to install it.

1, go to /usr/local/src directory and deflate the file.
sudo mv kqemu-version.tar.gz /usr/local/src/

2,
sudo ./configure
sudo make
sudo make install

3,After these process, I cannot see kqemu in /dev/. So I continue with the following code.

sudo mknod /dev/kqemu c 250 0
sudo chmod 666 /dev/kqemu

4,Active module KQEMU
sudo modprobe kqemu

By now, the kqemu appears and seems to work. But when I run the qemu with this kqemu, the problem comes. The screen in qemu can only active for one min or two, and then becomes black. The qemu stops. I cannot close the qemu window. And in the terminal the following message shows up.

===============error message ends here========================

I use f7 only for a couple of weeks and I truly don't know what this message means. Did I do something wrong? Please help me with this, because I have to use XP to run 3ds max to build the character. I am so worry about this.

Please help me! Thanks so much!!!

I forget one more question about that kqemu. That is every time when I start f7, the kqemu is not in /dev/, so I have to run the code I typed above and activate it, and then the kqemu can appears in /dev/. Then when I run qemu, the above problem comes up.

I hope that maybe help. Thanks so much!!!
