[Xen-users] scripts

[jacek burghardt <jaceksburghardt@xxxxxxxxx>]

I wonder if there is a way to for xen to run Âscript after guess is shutdown.

I would like to pass sound card from linux to hvm guess and then when hvm guest is shutdown back to linux. ÂScript can unload all usb modules and assign to hvm and back.

#!/bin/bash

if [ $# -ne 2 ]; then

  echo "Require PCI devices in format: Â<domain>:<bus>:<slot>.<function>"

  echo "Eg: $(basename $0) device_name 0000:00:1b.0"

  exit 1

fi

devicename=$1

pcidev=$2

for pcidev in $@; do

  if [ -h /sys/bus/pci/devices/"$pcidev"/driver ]; then

    echo "Unbinding $pcidev from" $(basename $(readlink /sys/bus/pci/devices/"$pcidev"/driver))

    echo -n "$pcidev" > /sys/bus/pci/devices/"$pcidev"/driver/unbind

  fi

  echo "Binding $pcidev to $devicename"

  echo -n "$pcidev" > /sys/bus/pci/drivers/$devicename/bind

  echo -n "$pcidev" > /sys/bus/pci/drivers/$devicename/new_slot

done
