Dear Openstack community, I am trying to setup a vm with bith pci-passthrough and cpu pinning. This is my flavor: [root@openstack-deployment ~]# openstack flavor show kudu.test.dedicated.tiny +----------------------------+--------------------------------------------------------------+ | Field | Value | +----------------------------+--------------------------------------------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | access_project_ids | None | | disk | 10 | | id | 7e241e94-1c50-4a92-9ce6-8abb272d79d8 | | name | kudu.test.dedicated.tiny | | os-flavor-access:is_public | True | | properties | hw:cpu_policy='dedicated', hw:pci_passthrough:alias='nvme:1' | | ram | 4096 | | rxtx_factor | 1.0 | | swap | | | vcpus | 2 | +----------------------------+--------------------------------------------------------------+ And this is how I create the vm: [root@openstack-deployment ~]# openstack server create --flavor kudu.test.dedicated.tiny --image centos7.5-image --nic net-id=hpc --security-group admin --key-name mykey --availability-zone nova:zeus-53.localdomain kudu-test-3-1 The problem is that the vm does not have the nvme pci device attached to it.
