The filename can be overridden but it expects a non-blocking source of entropy.
A typical invocation would be:
qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0
This can also be used with /dev/urandom by using the command line:
qemu -object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-pci,rng=rng0
