Hello,

I'm trying to run an x86 full system simulation using the --dual option, and 
I'm getting an error related to the voltage. Does anyone know how to make it 
work? I'm using the standard files from

http://www.m5sim.org/dist/current/x86/x86-system.tar.bz2

The command and the output are below. Thanks for any help!
Maciej

>the command:

build/X86/gem5.opt configs/example/fs.py 
--kernel=/home/maciej/iommus/simulations/x86-full-system-sims/binaries/x86_64-vmlinux-2.6.22.9
 
--disk-image=/home/maciej/iommus/simulations/x86-full-system-sims/disks/linux-x86.img
 --dual
