At start up of nova-compute service, the PCI stat pools are populated based on information in pci_devices table in Nova database. The pools are updated only when new device is added or removed but not on any device changes like device type. If an existing device is configured as SRIOV and nova-compute is restarted, the pci_devices table gets updated but the device is still listed under the old pool in pci_tracker.stats.pool (in-memory object). This patch looks for device type updates in existing devices and updates the pools accordingly. Change-Id: Id4ebb06e634a612c8be4be6c678d8265e0b99730 Closes-Bug: #1892361

Fixes `bug 1892361`_ in which the pci stat pools are not updated when an
|
|
existing device is enabled with SRIOV capability. Restart of nova-compute
|
|
service updates the pci device type from type-PCI to type-PF but the pools
|
|
still maintain the device type as type-PCI. And so the PF is considered for
|
|
allocation to instance that requests vnic_type=direct. With this fix, the
|
|
pci device type updates are detected and the pci stat pools are updated
|
|
properly.
