Examples from what I personally use:
https://github.com/riscv/meta-riscv
https://fedoraproject.org/wiki/Architectures/RISC-V/Installing#Boot_with_libvirt
(might be outdated)

If you are running machine with a properly working libvirt/QEMU setup:

VIRTBUILDER_IMAGE=fedora-rawhide-developer-20190703n0
FIRMWARE=fw_payload-uboot-qemu-virt-smode.elf
wget https://dl.fedoraproject.org/pub/alt/risc-v/disk-images/fedora/rawhide/20190703.n.0/Developer/$FIRMWARE
echo riscv > /tmp/rootpw
virt-builder \
    --verbose \
    --source https://dl.fedoraproject.org/pub/alt/risc-v/repo/virt-builder-images/images/index
\
    --no-check-signature \
    --arch riscv64 \
    --size 10G \
    --format raw \
    --hostname fedora-riscv \
    -o disk \
    --root-password file:/tmp/rootpw \
    ${VIRTBUILDER_IMAGE}

sudo virt-install \
    --name fedora-riscv \
    --arch riscv64 \
    --vcpus 4 \
    --memory 3048 \
    --import \
    --disk path=$PWD/disk \
    --boot kernel=$PWD/${FIRMWARE} \
    --network network=default \
    --graphics none \
    --serial log.file=/tmp/fedora-riscv.serial.log \
    --noautoconsole

The following does incl. SECCOMP v2 patch on top of 5.2-rc7 kernel.
