Starting VM with qemu-system-i386 using KVM causes looping
   ```
   qemu-system-i386 -accel kvm -cdrom gamebro.iso

Starting VM with qemu-system-i386 on Windows using WHPX works
   ```
   qemu-system-i386.exe -accel whpx -cdrom gamebro.iso
   ```
Starting other iso images works, e.g. https://cdimage.debian.org/mirror/cdimage/archive/10.8.0/i386/iso-cd/debian-10.8.0-i386-netinst.iso

   qemu-system-i386 -cdrom debian-10.8.0-i386-netinst.iso
