Comment # 11 on bug 989462 from Gary Ching-Pang Lin

I tested on Tumbleweed, and this command works for me:

qemu-system-aarch64 -m 1024 \
  -cpu cortex-a57 \
  -M virt \
  -serial stdio \
  -drive
if=pflash,format=raw,readonly,file=/usr/share/qemu/aavmf-aarch64-code.bin \
  -drive if=pflash,format=raw,file=aavmf-aarch64-vars.bin

Just submitted the newer OVMF to Leap 42.1.
