hi
just following up form yesterday.
i just finished testing the pci numa policy feature
and i can confirm that the prefer policy which allow use of non
local pci devices does not work.
the test case was relitively simple
1 host with 2 numa nodes
1 pci device attach to numa node 0
and vcpu pin set configured to allow only numa node 1
in this case booting a vm with a passthrough alias and a passthrough alias
fails.
[stack@cloud-3 devstack]$ openstack flavor show 42

passthrough_whitelist = { "address": "0000:01:00.1" }
alias = { "vendor_id":"8086", "product_id":"10c9", "device_type":"type-PF",
"name":"nic-pf", "numa_policy": "preferred"}
removeing the hw:numa_nodes='1' extra spec allow the vm to boot as it nolonger
has a numa topology.
the vm passes scheduling in both casess but when the vm has a virtual numa
toplogy of 1 node
we fail in the resocue tracker on the compute node when claiming resouces for
the instance.
i will submit a bug for this and repose the spec next week to track closing
this gap.
