(7)執行qemu-system-x86_64 -machine 虛擬機器，終於可載入GNOME
# qemu-system-x86_64 -machine accel=kvm -m 1024 -drive if=pflash,format=raw,unit=0,file=/usr/share/edk2/ovmf/OVMF_CODE.fd,readonly=on -drive if=pflash,format=raw,unit=1,file=$HOME/OVMF_VARS.fd -drive if=ide,format=raw,file=$HOME/uefi.img -net bridge,br=br0 -net nic,model=virtio
(8)qemu虛擬機器執行成功的畫面如下：
