Hi Leo! > What does the argument "filename=/dev/random" do? Does it use the host's > /dev/random to provide entropy to the QEMU guest?
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 Stefan [1] https://www.qemu.org/docs/master/system/invocation.html#hxtool-10
