On one host I am using qemu-kvm from qemu-system-x86-0.13.0-1.fc14.x86_64, and on another /usr/local/qemu-kvm.latest/bin/qemu-kvm where latest was qemu-kvm.git on Oct 11. Both work fine. I like this route (using screen and stdio -- no piping) so that I still have a usable console. Maybe it's a difference between qemu and qemu-kvm. David
