Definitely prevent stubborn devices from being bound by the host driver in PCI passthrough scenario

Scenario

You're running a KVM-based virtualization. You want to do PCI/PCIe passthrough of some device. You don't want it to attach to the host OS at all.

Your device looks like that:

00:1f.2 SATA controller [0106]: Intel Corporation 6 Series/C200 Series Chipset Family SATA AHCI Controller [8086:1c02] (rev 05)
	Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family 6 port Desktop SATA AHCI Controller [103c:330d]
	Kernel driver in use: ahci
	Kernel modules: ahci
