At this moment it is not possible to launch a 'riscv64' domain of type 'qemu' (i.e. TCG) and machine 'virt' in a x86 host:
$ sudo ./run tools/virsh start riscv-virt1 error: Failed to start domain 'riscv-virt1' error: this function is not supported by the connection driver: cannot update guest CPU for riscv64 architecture
I get a different error message, specifically
unsupported configuration: CPU mode 'custom' for riscv64 qemu domain on x86_64 host is not supported by hypervisor
Ha, I believe the patch is still relevant but I did a serious mess in the commit message :(
The difference between what we're seeing is that I used a QEMU from riscv-to-apply.next from the maintainer tree [1] instead of master.
I was thinking about libvirt's master branch rather than QEMU's, but that makes sense. I'll check out v2 after building QEMU from the appropriate branch.

target/riscv: add query-cpy-definitions support
Since this hasn't made its way into master yet, maybe you can still get the maintainer to s/cpy/cpu/ for you? :) -- Andrea Bolognani / Red Hat / Virtualization
