Can you look if you have errors in the nova-computes log?

Also check if you passed the PciPassthroughFilter in the nova-scheduler log

Subject: [Openstack] Issue with assignment of Intel’s QAT Card to VM 
(PCI-passthrough) using openstack-mitaka release on Cent OS 7.2 host


Hi All,

I want the Intel’s QAT Card to be used for PCI Passthrough device. But to 
implement PCI-passthrough, when I launch a VM using a flavor configured for 
passthrough, it  gives the below errors in nova-conductor.log and instance goes 
into Error state. Note that, I have installed
openstack-mitaka release on host (Cent OS 7.2).  Can anyone please have a look 
into the below stated and let me know if I have missed anything or done 
anything wrong?  Thank you in advance for your support and time.


When I create an instance, this error is output in nova-conductor.log.
