Unfortunately, both qemu and kvm don't appear to have a reliable way to hard-reboot - normal reboots don't reset the 0xc0000-0xfffff memory. I've worked around this on qemu by manually resetting that memory. However, kvm doesn't keep a pristine copy of the bios at 0xffff0000. Until this is fixed, this patch series will cause a soft-reboot on kvm to result in a shutdown instead of a reboot.
Why is there a difference between qemu and kvm here? What patch did you use for qemu and why doesn't it work for kvm?
