I'm testing KVM device(pci) pass-through with new 3.x kernel (RHEL 7.0) It seems new device pass-through framework, VFIO, has been merged since kernel 3.6. Before VFIO (prior pci-stub) we could simply assign each PF or VF to different guest VM freely but with VFIO, kernel strictly ...
The vfio_pci ids= should be a comma separated list of all vendor-id:device-id pairs you want stubbed by the VFIO driver. Remember that you must pass through all PCI devices in the same IOMMU group. In this case here, I’m passthrough through both the audio and video components of the...
