Comment 14 for bug 1029889

This makes me wonder whether one of the packages installed on the first machine is corrupt. Does sha1sum /var/cache/apt/archives/qemu*ubuntu14* show the same results on both systems?

The ps -ef output confirms that kvm is not being called by libvirt with -pidfile, so the change from ubuntu13 to ubuntu14 (which only deals with handling of the pid file) all the more doesn't seem to make sense.
