I am having the following error when I run the executable script "sudo /usr/vm1" :

cat: /sys/bus/pci/devices//vendor: No such file or directory cat: /sys/bus/pci/devices//device: No such file or directory /usr/vm1: line 12: echo: write error: Invalid argument

Below is the script code :

#!/bin/bash

configfile=/etc/vfio-pci1.cfg

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

}

modprobe vfio-pci

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

-boot menu=on

exit 0

What could be the cause of the problem ? The VM OS is not displayed at all
