"Failed to redirect device" if device is redirected to another VM
Submitted by Lasse Schuirmann
Steps to reproduce:
- Start a VM
- Redirect a USB device to it
- Start another VM in a second window
- Redirect the same USB device to this one
"Failed to redirect device" error message.
If a USB device is already redirected to another running VM we either shouldn't offer redirection or show a hint or so that this device is not redirectable until unredirected from the other VM.
