• installed a GPU on a compute node, configured kernel etc and now it is using the vfio-pci driver • set [pci]/device_spec = { "vendor_id": "10de", "product_id": "1ff2" } on compute node (formerly [pci]/passthrough_whitelist) and restarted openstack-nova-* • On the controller node set [pci]/alias: { "vendor_id":"10de", "product_id":"1ff2", "device_type":"type-PCI", "name":"nvidia-t400" }, [filter_scheduler]/enabled_filters = PciPassthroughFilter, [filter_scheduler]/available_filters = nova.scheduler.filters.all_filters and restarted openstack-nova-*
Did you add the alias line to the compute node as well? The controllers need just the alias, the compute needs the alias and device_spec. https://docs.openstack.org/nova/latest/admin/pci-passthrough.html#configure-... --Dan
