Title:
SRIOV pci_numa_policy dosen't working when create instance with
'cpu_policy' and 'num_nodes'
Status in OpenStack Compute (nova):
New
Bug description:
Description
===========
When we create a sriov instance, which flavor has 'cpu_policy', 'numa_nodes'
property, it's also has 'pci_numa_policy=preferred' property that indicate we
are able to allocate pci devices and vcpu in different numa node.
However, in some cases, it didn't work, because the fake pci request, which
produced by nova flavor and [pci] alias in nova.conf hasn't write related
information (such as pci_numa_policy, alias_name and some spec info) into real
pci_requests (which contain port_id). So, in nova/pci/stats.py function 'def
_filter_pools_for_numa_cells', there will filter all pci devices.
Environment
===========
Openstack Queen
compute node information: Two numa nodes(node-0 node-1), SRIOV-PCI devices
associated with NUMA node-1, but cpus of node-1 have run out.
Steps to reproduce
==================
nova.conf
[pci]
alias = {"name": "QuickAssist","product_id": "10ed","vendor_id":
"8086","device_type": "type-VF","numa_policy": "preferred"}

Expected result
===============
The instance could be created.
Actual result
=============
Schedule failed.
