The only problem is that I've no idea when it will be possible to finally disable the init script (shipped in Debian and other distros) to load the module based on /proc/cpuinfo contents. It will do nothing on kernels with this (or kvm-intel) change applied, but we still need to support older kernels without that feature... :) Josh, and I'm sure you will be the first who'll file a bugreport against qemu-kvm in Debian requesting the startup script to be removed!.. ;)) Thanks, /mjt
