Wenn ich die Weiterleitung der gvtg Grafikkarte entferne bootet die Maschine wieder.

Sieht so aus als wenn irgendwo die mdev ID falsch an die KVM übergeben wird:
00000000-0000-0000-0000-000000000000 müsste 00000000-0000-0000-0000-000000000120 sein.
Angelegt und entfernt wird das Device einwandfrei.
Es hapert also nur an der Übergabe an die KVM CMD.
