melanie witt 79df36fecf Prevent archiving of pci_devices records because of 'instance_uuid'
Currently in the archive_deleted_rows code, we will attempt to clean up
"residue" of deleted instance records by assuming any table with a
'instance_uuid' column represents data tied to an instance's lifecycle
and delete such records.

This behavior poses a problem in the case where an instance has a PCI
device allocated and someone deletes the instance. The 'instance_uuid'
column in the pci_devices table is used to track the allocation
association of a PCI with an instance. There is a small time window
during which the instance record has been deleted but the PCI device
has not yet been freed from a database record perspective as PCI
devices are freed during the _complete_deletion method in the compute
manager as part of the resource tracker update call.

Records in the pci_devices table are anyway not related to the
lifecycle of instances so they should not be considered residue to
clean up if an instance is deleted. This adds a condition to avoid
archiving pci_devices on the basis of an instance association.

Closes-Bug: #1899541

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
