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.
