any particular reason not using neutron api with port-create?
any how can you add the output of lspci -tvn ?

Hi Alon,
Thank you for your response.
I am using Nova flavor definition. But when I launch an instance
using this new flavor, it goes into an error state
nova boot --flavor 4 --key_name oskey1 --image

Note that, If I set the flavor as (#nova flavor-key 4 set

you please suggest , where I am wrong and the way to solve this ?

Which method you are using?
Neutron sriov plugin? Nova (via flavor definition)? Neutron without

Hi ,
Can anyone please suggest how to assign multiple VF devices to
VM instance using open-stack openstack-mitaka release? Thank you in
advance for your time and support.

Hi All,
I have installed open-stack openstack-mitaka release on CentO7
system . It has two Intel QAT devices. There are 32 VF devices
available per QAT Device/DH895xCC device.

Changed the nova configuration (as stated below) for exposing VF

pci_alias = {"name": "QuickAssist", "product_id":

"vendor_id": "8086", "device_type":

pci_passthrough_whitelist =

Restarted the nova compute, nova API and nova scheduler service

Thereafter it shows all the available VFs (64) in nova database
upon select * from pci_devices. Set the flavor 4 to allow
passing two VFs to instances.
