Riscv64 KVM services SBI calls internally, so OpenSBI is not used in such setups. Restrict the "-bios" flag accordingly. Thanks: Andrei, Drew.

"acpi=off" is arguably unusual with UEFI guest OSes; add a note to explain it. Original explanation by Drew Jones.

Direct (fw_cfg) kernel boot works on the RiscVVirt firmware platform too; I've tested it after extracting the kernel, initrd, and kernel command line from "openSUSE-Tumbleweed-RISC-V-E20-efi.riscv64.raw". Document this type of boot, because at least historically, fw_cfg kernel boot was implemented differently between OVMF and ArmVirtQemu. Thanks: Drew, Sunil.
