Public bug reported:

Hi, this is my 1st time write this report at Launchpad.

===Description===
I'm using Mitaka installed by Fuel 9.2, and I meet a issue that the info didn't remove at pci_devices table in Nova Database after I removed one of the device from compute node and nova.conf


===How did I reproduce?===

1. Plug two different model PCI devices and add two PCI devices
information into nova.conf in target compute node and each control node
by following format:


2. Restart nova-api, nova-scheduler, and nova-compute.

Compute node only shows the last device I add.

But if I do some actions on instance with the flavor contained PCI
passthrough info, it will be normal.

And database info is correct.


3. Remove one of the PCI device info from nova.conf (included target compute and controllers), restart services, shutdown the compute node and unplug the device.

(Note: The card ID of what I remove is 1002:68c8)

Power on the compute code and check nova-compute log, the report is
correct.

===Expected result===
The info of removed device should be deleted or stayed at "DELETED" status in Nova DB.

===Actual result===
The info of removed device still exist and stayed at "AVAILABLE" status in Nova DB.


===Log and configs===
