PCI passthrough local_override.yaml example #135

Closed adduarte closed 3 years ago

adduarte commented 3 years ago

All the necessary parameters to configured pci passthrough can be specified in the local_override.yaml file

/lgtm

We might refine this if the need arises, but I'm happy to wait to see if that happens.

/hold Turns out we can proably do all of this by just including the correct fields into standalone_parameters.yaml like so: 

  #0b:00.0 VGA compatible controller [0300]: Matrox Electronics Systems Ltd. G200eR2 [102b:0534] (rev 01)
  NovaSchedulerDefaultFilters: ['RetryFilter','AvailabilityZoneFilter','ComputeFilter','ComputeCapabilitiesFilter','ImagePropertiesFilter','ServerGroupAntiAffinityFilter','ServerGroupAffinityFilter','PciPassthroughFilter','NUMATopologyFilter']
  NovaSchedulerAvailableFilters: ["nova.scheduler.filters.all_filters","nova.scheduler.filters.pci_passthrough_filter.PciPassthroughFilter"]
  nova::pci::aliases: [{"name": "VGAalias","vendor_id": "102b","product_id": "0534","devic_type": "type-PCI"}]

  NovaPCIPassthrough: [{"vendor_id": "102b", "product_id": "0534"}]
  KernelArgs: "iommu=pt intel_iommu=on"

here is the documentation on how to do it. Is pretty simple, the only question is where we can add all of those, because the manual expects a separation of controller and compute node, but this all in one single place. https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html/configuring_the_compute_service_for_instance_creation/configuring-pci-passthrough
