<div dir="ltr">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. 2016-06-06 05:42:42.005 4898 WARNING nova.scheduler.utils [req-94484e27-1998-4e3a-8aa8-06805613ae65 266f5859848e4f39b9725203dda5c3f2 4bc608763cee41d9a8df26d3ef919825 - - -] Failed to compute_task_build_instances: No valid host was found.
