Comment # 34 on bug 1199355 from Stefan Seyfried

This is an example commandline of the qemu invocation:

/usr/bin/qemu-system-aarch64 -nodefaults -no-reboot -nographic -vga none -cpu
host -enable-kvm -M virt,accel=kvm,usb=off,gic-version=host -sandbox on -object
rng-random,filename=/dev/hwrng,id=rng0 -device virtio-rng-device,rng=rng0
-object iothread,id=io0 -runas qemu -net none -kernel
/var/cache/obs/worker/root_2/.mount/boot/kernel -initrd
/var/cache/obs/worker/root_2/.mount/boot/initrd -append

socket,id=monitor,server=on,wait=off,path=/var/cache/obs/worker/root_2/root.qemu/monitor
-mon chardev=monitor,mode=readline -smp 2

If there is just another command line option for reverting this last qemu
change, I could try replacing it with a wrapper script. If it involves more
than just adding an option, it's probably not easily doable.
