执行 QEMU shell 脚本时无输出

我遇到一个问题，当我运行以下命令时终端中没有输出：

sudo ./windows10vm.sh

我使用的脚本来自本教程来自 Linux Mint 论坛，我稍作修改

#!/bin/bash

configfile=/etc/vfio-pci.cfg
vmname="windows10virt"

vfiobind() {
   dev="$1"
        vendor=$(cat /sys/bus/pci/devices/$dev/vendor)
        device=$(cat /sys/bus/pci/devices/$dev/device)
        if [ -e /sys/bus/pci/devices/$dev/driver ]; then
                echo $dev > /sys/bus/pci/devices/$dev/driver/unbind
        fi
        echo $vendor $device > /sys/bus/pci/drivers/vfio-pci/new_id

}


if ps -A | grep -q $vmname; then
   echo "$vmname is already running." &
   exit 1

else

   cat $configfile | while read line;do
   echo $line | grep ^# >/dev/null 2>&1 && continue
      vfiobind $line
   done

# use pulseaudio
export QEMU_AUDIO_DRV=pa

cp /usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd /tmp/my_vars.fd
