This is the only way to let libSDL to open framebuffer console on the same VT as your X is running, and thus ruin X -- only when running as root it has necessary permissions to do that. This is on the same theme as complaining that `rm -rf /' destroys your system - yes it does when run as root, don't do that. I understand this is not right comparison - rm is designed to remove files, while kvm is not designed to ruin X session. I'm retitling this bug to reflect actual situation more closely, and downgrading it to a wishlist, so that the information will be easy to find. Maybe we can actually do something with this someday.
