Title: [pci-passthrough] nova-compute fails to start Status in OpenStack Compute (Nova): Fix Released Bug description: Created a guest using nova with a passthrough device, shutdown that guest, and disabled nova-compute (openstack-service stop). Went to turn things back on, and nova-compute fails to start.
