Instead of running the generic block fuzzer with QCOW, it's better to
use a RAW file since it's less complex and it will focus on virtqueues.

Now that both synchronous and asynchronous backends rely on the
asynchronous version of virtio-block (namely BlockIoUring), we can
get rid of the synchronous version (namely Block).

from crosvm and adapted to our code.
