That doesn't work with a CD image.  When I try to run
http://download.opensuse.org/ports/riscv/tumbleweed/iso/openSUSE-Tumbleweed-NET-riscv64-Media.iso
with qemu, the initrd fails to load.

$ qemu-system-riscv64 -M virt -nographic -serial mon:stdio -smp 4 -m 8g -kernel 
u-boot.bin -drive 
format=raw,if=virtio,media=cdrom,file=openSUSE-Tumbleweed-NET-riscv64-Media.iso
