Comment # 8 on bug 989462 from James Fehlig

Heh, now I'm unsure about the proper way to invoke qemu with the aavmf images. 

For example on x86_64, with a guest using persistent UEFI variables, qemu is
invoked as

-drive
file=/usr/share/qemu/ovmf-x86_64-ms-code.bin,if=pflash,format=raw,unit=0,readonly=on
-drive
file=/var/lib/libvirt/nvram/sles12sp2a2-ovfm-kvm_VARS.fd,if=pflash,format=raw,unit=1

On ARM, with a guest not using persistent variables, the linaro docs say to use

-bios /path/to/code-image

With persistent variables, the linaro docs recommend

-pflash /path/to/code-image -pflash /path/to/var-image

Gary, Alex, Andreas: Can you verify the correct qemu invocation for aavmf with
and without persistent variables? Thanks.
