Can not attach device via stdin but via file

[d3vr4ndOm]

I was not able to attach the device with the following script. As workaround a write a temporary XML file and pass the path as parameter.
I changed the script to:

cat < /tmp/device2attach

EOT

virsh ${COMMAND} ${DOMAIN} --file /tmp/device2attach
