Fedora/RISCV uses OpenSBI + U-Boot setup which loads extlinux configuration file from boot media and then continues booting Linux kernel.
pcie-root-port was finally enabled for RISC-V in QEMU 4.0.0. PCI is now default instead of MMIO starting libvirt v5.3.0 with QEMU 4.0.0 or newer. Simply put this means that devices are connected over VirtIO PCI (incl. storage, i.e. boot media).
Andrea Bolognani (Red Hat, Virtualization) noticed that Fedora/RISCV doesn't boot using libvirt. This is due to U-Boot not detecting boot media.
These two small patches address the issue (tested by me and Andrea).
