Hi Leo!

Yes, see [1]:
“-object rng-random,id=id,filename=/dev/random
Creates a random number generator backend which obtains entropy from a device
on the host. The id parameter is a unique ID that will be used to reference
this entropy backend from the virtio-rng device. The filename parameter
specifies which file to obtain entropy from and if omitted defaults to
/dev/urandom.”
Bye
