But I thought that maybe it will be more useful for you to try it on your own. So I've prepared some minimal debian installation which you could download here (apx 163M bzipped): > > http://fi.muni.cz/~xracek/debian.img.bz2 > > Password: > root/asdfgh > > Here is my config for guest kernel: > > http://fi.muni.cz/~xracek/config > > I use > > qemu-kvm -m 1500 -hda debian.img -kernel linux/arch/x86/boot/bzImage -append "root=/dev/sda1" Um. I'd expect the image to be self-contained, no external kernel. I wanted to do a quick test to see if it fails on my machine too, d/loaded debian.img.bz2 but there's no kernel. So.. no quick test for you ;) > After logging in just run "sh runtest.sh". This leads to crash in my case (host: Intel Core i5-2540M, kernel 3.5.2-1.fc17.x86_64, qemu 1.0.1). With all the above, this "runtest.sh" is informationally equal to your disk image. /mjt -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
