Description Marko Myllynen 2016-11-14 08:14:11 UTC

Description of problem:
http://docs.openstack.org/admin-guide/compute-pci-passthrough.html explains most of the steps needed to configure PCI passthrough (!=SR-IOV) but doesn't explicitly mention that VT-d needs to be enabled in BIOS and kernel parameters intel_iommu=on iommu=pt should be used (on Intel). The document also uses type-PF instead of type-PCI for pci_alias, the difference between type-PCI / type-PF / type-VF should also be explained.

It would be nice to have this added to the RH OSP documentation. The most common use case for this would probably be HPC/GPU.

Thanks.
