The aliases need to be defined in your conf files on both the conductor and the compute nodes. If that's the case let me know and I'll take a closer look when I get to my desk. it needs to be defined on the nova api server config and the nova compute config due to how the numa afinity policies work. at least i think that is the reason. stephen dug into this while trying to fix https://bugs.launchpad.net/nova/+bug/1805891 https://review.openstack.org/#/c/624444/2

its documented in the docs i linked in my previous reply https://docs.openstack.org/nova/latest/admin/pci-passthrough.html#configure-... and https://docs.openstack.org/nova/latest/admin/pci-passthrough.html#configure-... stephen has another patch up to make it even more explicit https://review.openstack.org/#/c/624445/ the conductor should not need the alias defiend.

Dear openstack community,

I am trying to setup pci passthrough for multiple devices types but I am getting an error while creating a new vm.

This is my pci section in nova.conf compute node

[pci] passthrough_whitelist = [{ "vendor_id": "10de", "product_id": "1db1" }, { "vendor_id": "15b3", "product_id": "1016" }] alias = { "vendor_id":"10de", "product_id":"1db1", "device_type":"type-PCI", "name":"nv_v100" } alias = { "vendor_id":"15b3", "product_id":"1016", "device_type":"type-VF", "name":"mlnx_connectx4" }

I also tried this

[pci] passthrough_whitelist = [{ "vendor_id": "10de", "product_id": "1db1" }, { "vendor_id": "15b3", "product_id": "1016" }] alias = [{ "vendor_id":"10de", "product_id":"1db1", "device_type":"type-PCI", "name":"nv_v100" }, { "vendor_id":"15b3", "product_id":"1016", "device_type":"type-VF", "name":"mlnx_connectx4" }]

And this is the error I am getting when I try to create a new vm:

# openstack server create --flavor sriov.small --image centos7.5-image --availability-zone nova:zeus- 59.localdomain vm-sriov-test PCI alias mlnx_connectx4 is not defined (HTTP 400) (Request-ID: req-aebb2d05-a557-428b-b2c6-090c16dc7c76)

how can I setup multiple aliases for different devices?
