This config file uses accel = "kvm", so it can only work on Linux. It also uses two hard-coded image names which we have to replace with unique temporary files to avoid race conditions. So after creating the temporary image files, we also have to create a copy of the config file where we replaced the hard-coded image names. Once everything is in place, we can start QEMU with this config file and check that everything is available in QEMU.
