No, the 8.2.2 drivers should all be signed now. I'm not aware of an unsigned 
build being available for download any more.

This should not happen with the drivers currently available. If it does then 
there is something wrong.

The XCP-NG drivers *should* be fine. I have not tried them myself for a while 
though. The fact they are bundled with an installer does make them more 
convenient so I suggest you do give them a go.
