commit c2c3b97259258eec3c98feabde3b411b519eae6e Author: Moshe Levi <[email protected]> Date: Mon Apr 18 14:33:59 2016 +0300 pci: Move PCI devices and PCI requests into migration context When resizing guest to flavor with pci passthrogth, we need to drop the old pci devices and allocate new ones. To be able to do that we are leveraging the migration context (that used only for NUMA). Adds old and new PCI devices/ PCI requests into the MigrationContext object and uses the nova.pci.request.get_pci_requests_from_flavor() function to grab the set of requested PCI devices during a migration. Then, in the resource tracker's _update_usage_from_migration() call, we use the old and new PCI devices and PCI requests stored in the MigrationContext to properly account for changes.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1368201 Title: resize with PCI devices doesn't work Status in OpenStack Compute (nova): Fix Released Bug description: In icehouse, if an active instance without PCI passthrough devices is resized with PCI passthrough devices being added in the new flavor, the instance will be reported as ACTIVE after resizing, but becomes inaccessible. Worse, the whole compute service seems to be hosed, and killing it would cause the compute node to hang. if an active instance with PCI passthrough devices is resized with more PCI passthrough devices in the new flavor, the resulting PCI devices in the instance's domain xml are more than being requested, and the same symptoms as described above will result as well.
