The instructions should work.  RISC-V Fedora started a mass rebuild in
mid January, but the images listed by virt-builder should be OK.  Also
keep in mind that you could be hitting a qemu bug, and you might want
to try a different qemu version or top of tree for the qemu sources.
There is a known bug in the RISC-V qemu-4.2 port that can causes FP
programs to fail for instance, a patch was contributed last week to
fix this.  It helps if you mention exactly which fedora image you are
using and exactly which qemu version you are using.
