Pass-through Networking in DomU not working

[Pedro Miguel Veiga de Almeida e Silva <up201806445@xxxxxxxxxxx>]

Hi,

I found this video https://www.youtube.com/watch?v=UfiP9eAV0WA and tried to boot a DomU with a network device assigned in a xilinx zcu106 using XEN and petalinux. Unfortunately, even though I think that i followed all the right steps it outputs this error when it boots. (this is a DomU created through xl command the same way just to see the code clearly).

Thank you for the help.
