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
bc859dc5-103b-428b-814f-d36e59009454 --nic

Here goes the output of nova-scheduler.log

Note that, If I set the flavor as (#nova flavor-key 4 set
"pci_passthrough:alias"="QuickAssist:1") , it assigns a single VF to VM
instance. Getting issue when I try to assign multiple VFs per VM. Can
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
sriov plugin (which I think is the best)

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
( via PCI-passthrough) to the instances.
pci_alias = {"name": "QuickAssist", "product_id": "0443",
"vendor_id": "8086", "device_type": "type-VF"}
pci_passthrough_whitelist =
[{"vendor_id":"8086","product_id":"0443"}}]
Restarted the nova compute, nova API and nova scheduler service
service openstack-nova-compute restart;service
openstack-nova-api restart;systemctl restart
openstack-nova-scheduler;
scheduler_available_filters=nova.scheduler.filters.all_filters
scheduler_default_filters=RamFilter,ComputeFilter,AvailabilityZoneFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,PciPassthroughFilter
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.
