I forgot to mention that I did read http://gem5.org/Compiling_a_Linux_Kernel and http://gem5.org/Linux_kernel but they don't seem to answer what I think I should be asking.

Segmentation fault I have created an .img file for Ubuntu 12.04 64bit using QEMU and am able to boot into it using QEMU. Then I can run ramspeed to verify it works within the image. My question is where do I get the kernel I need to specify when I run the following: build/X86/gem5.opt configs/example/fs.py --disk-image=/home/bpayne/full_system_images/disks/ubuntu-x86_64_1204.img --kernel=/home/bpayne/full_system_images/binaries/x86_64-vmlinux-2.6.22.9 I tried --kernel=/boot/vmlinux-3.2.0-29-generic which is on the host, but that file is only 5MB (rather than the 50MB kernel which was downloaded from m5sim.org. I have compiled the kernel before, but didn't produce the file gem5 is looking for.
