Hi all,
To reduce complexity in configuring SR-IOV I want to deprecate the
supported_pci_vendor_devs option [1] in the neutron-server ml2 config.
This option is doing extra validation that pci vendor id and product id
provided by nova in the neutron port binding profile is matching to the vendor
id and product id in supported_pci_vendor_devs.
In my opinion this is redundant, nova-scheduler is the point to do validation
and select a suitable hypervisor.
The compute node is already validating this through the
pci_passthrough_whitelist option in nova.conf [2].
I don't see a reason why the neutron-server should validate the pci vendor_id
and product_id again from the neutron port binding profile.
If there is good reason to keep it please let me know, otherwise I will
deprecate it.
[1] - supported_pci_vendor_devs = ['15b3:1004', '8086:10ca']
[2] - pci_passthrough_whitelist =
{"address":"*:06:00.*","physical_network":"physnet1"}
Thanks,
Moshe
