After the scheduler selected a target host and allocated an allocation candidate that is passed the filters nova need to make sure that PCI claim will allocate the real PCI devices from the RP which is allocated in placement. Placement returns the request group - provider mapping for each allocation candidate so nova can map which InstancePCIRequest was fulfilled from which RP in the selected allocation candidate. This mapping is then recorded in the InstancePCIRequest object and used during the PCI claim to filter for PCI pools that can be used to claim PCI devices from. blueprint: pci-device-tracking-in-placement Change-Id: I18bb31e23cc014411db68c31317ed983886d1a8e |
