...s (e.g. multiqueue) have function numbers which are not a multiple of 8. The simple hypervisor Jailhouse passes subdevices directly w/o providing a virtual PCI topology like KVM. As a consequence a PCI passthrough from Jailhouse to a guest will not be detected by Linux. Based on patch by Benedikt Spranger, adding Jailhouse probing to avoid changing the behavior in the absence of the hypervisor.
