I don’t suppose one of you riscv folks would like to contribute riscv support to virtme?  virtme-run —arch=riscv would be quite nice, and the total patch should be just a couple lines.  Unfortunately, it helps a lot to understand the subtleties of booting the architecture to write those couple lines :)
