Download the latest disk image

Go to this link for the nightly builds and select the most recent (top) build. Look for the -sda.raw.xz file and download it. It will usually be quite large, around 200-300 MB.

unxz Fedora-Developer-Rawhide-xxxx.n.0-sda.raw.xz

The disk image is partitioned, but usually we need a "naked" filesystem. There are several ways to get this, but the easiest is:

guestfish -a Fedora-Developer-Rawhide-xxxx.n.0-sda.raw \
    run : download /dev/sda1 Fedora-Developer-Rawhide-xxxx.n.0-sda1.raw

This creates a naked ext4 filesystem called *-sda1.raw which can be used in qemu or booted on the HiFive Unleashed board.

Boot under qemu

You will need a very recent version of qemu. If in doubt, compile from upstream qemu sources.

Get bbl from here or compile it from source.

qemu-system-riscv64 \
    -nographic \
    -machine virt \
    -smp 4 \
    -m 2G \
    -kernel bbl \
    -object rng-random,filename=/dev/urandom,id=rng0 \
    -device virtio-rng-device,rng=rng0 \
    -append "console=ttyS0 ro root=/dev/vda" \
    -device virtio-blk-device,drive=hd0 \
    -drive file=Fedora-Developer-Rawhide-xxxx.n.0-sda1.raw,format=raw,id=hd0 \
    -device virtio-net-device,netdev=usernet \
    -netdev user,id=usernet,hostfwd=tcp::10000-:22

Install on the HiFive Unleashed SD card

The naked ext4 filesystem can be copied over the second partition of the SD card.

You can also build a custom bbl+kernel+initramfs to boot directly into the SD card using these sources.

Install on the HiFive Unleashed using NBD server

Look at https://github.com/rwmjones/fedora-riscv-kernel in the sifive_u540 branch. This is quite complex to set up so it's best to ask on the #fedora-riscv IRC channel.
