There's no system_reboot in either kvm nor qemu. I see two solutions
for wireing up domainReboot(). Either qemu/kvm accepts a parameter to
system_powerdown to signal that we should restart the vm instead of
simply shutting down or we simply send 
"sendkey ctrl-alt-delete"
to the monitor which might be very fragile though. Both solutions depend
on the os in the vm doing the right thing (acpi event handling in the
first case).
