This is really a show-stopper and spoils the otherwise solid solution to
use Ubuntu and KVM for virtualization.

Why did nobody propose yet to shut down the VMs by the qemu-kvm script?
I think "stop qemu-kvm" should try to shutdown all running kvms and kill
them after a timeout, independently of libvirt. This would also work for
instance, if libvirtd has been stopped before for other reasons and then
the system is rebooted. With the monitor (which is accessible after
libvirtd has been stopped) you can send a "system_powerdown" command.

At the moment "stop qemu-kvm" just removes the kvm kernel modules. Maybe
this is the explanation, why the kvm processes get killed? (Well,
normally not, the modprobe -r should not succeed, as long as the module
is in use. I cannot try it at the moment.)
