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.
Conflicts:
nova/tests/functional/libvirt/test_pci_sriov_servers.py
To avoid the conflicts and make the new functional test execute,
following changes are performed in the new test case
- Passing hostname as argument to self._get_connection() is not
supported in stable/stein and hence dropped the argument.
- Compute nodes cannot be retreived by host and nodename should
also be included in stable/stein. So modified the function call
to use objects.ComputeNode.get_by_host_and_nodename instead.
