Just in case someone need that little script to copy paste in dom0
Use case :
I have two USB key. But I will plug them on the same port. So for qvm-usb, they will have the same port number so I can't use --persistent as : - I want USB A to automatically attach to Vault - USB B to stay on usb-net
I did it fast, I will improve it later
#!/bin/sh
while true
do
usb=$(qvm-usb| grep usbA)
#echo Result + $usb
if [ -n "$usb" ];
then
qvm-usb attach Vault sys-net:2-2
echo "Attach"
else
qvm-usb detach Vault sys-net:2-2
echo "Detach"
fi
sleep 5
done
