addition of -monitor stdio

[030]

sudo qemu-system-x86_64 -enable-kvm \
        -machine q35 -smp sockets=1,cores=1,threads=2 -m 2048 \
        -usb -device usb-kbd -device usb-tablet -rtc base=localtime \
        -net nic,model=virtio -net user,hostfwd=tcp::4444-:4444 \
        -drive file=snapshot.img,media=disk,if=virtio \
        -loadvm windows

I added -monitor stdio to ensure that the windows-ie11 could be started and subsequently be saved as windows-edge

sudo qemu-system-x86_64 -enable-kvm \
        -machine q35 -smp sockets=1,cores=1,threads=2 -m 2048 \
        -usb -device usb-kbd -device usb-tablet -rtc base=localtime \
        -net nic,model=virtio -net user,hostfwd=tcp::4444-:4444 \
        -drive file=snapshot.img,media=disk,if=virtio \
        -monitor stdio \
        -loadvm windows-ie11
