We do not go through the loader > there when we are starting a FreeBSD guest, correct? bhyveload is effectively the loader in this case. It runs the normal loader scripts and logic and so would load the guests's /boot/entropy and pass it to the guest kernel as metadata just like the regular loader. In addition, bhyve also supports virtio-rng which is another way to provide entropy to guest OS's. That's why in my reply I focused on qemu for mips (or riscv) as for x86 hypervisors there are existing, somewhat-standarized solutions for the hypervisor to provide entropy to the guest. -- John Baldwin
