Command line? I tried with
x86_64-softmmu/qemu-system-x86_64 \
-pflash /usr/share/edk2/ovmf/OVMF_CODE.fd \
-pflash /usr/share/edk2/ovmf/OVMF_VARS.fd \
--enable-kvm -M q35 -debugcon stdio \
-global isa-debugcon.iobase=0x402 \
-net nic,model=virtio \
-net bridge,helper=/usr/libexec/qemu-bridge-helper,br=virbr0 \
-snapshot foo.raw
and after the above lines I get:
Select Item: 0x19

(but I'm using a different OVMF build,
edk2-ovmf-20161105git3b25ca8-2.fc25.noarch; dinner time now).
Thanks,
