This is due to https://review.openstack.org/#/c/202616/

The kilo node can't understand 1.2 PCIDeviceList.

Then when kilo compute node retry building instance request send to liberty conductor will get error as below:

This is due to https://github.com/openstack/nova/blob/master/nova/scheduler/utils.py#L59 didn't return True anymore, because the kilo node renturn InstanceV1, not InstanceV2.

Correct Instance type check to work with InstanceV1

    When Liberty controller running with Kilo compute node, the Kilo
    compute node will send the InstanceV1 to the Liberty controller.
    Then all the checks like "isinstance(instance, objects.Instance)"
    on the Liberty controller won't works. Because objects.Instance
    pointed to objects.InstanceV2 now.

This patch corrects all the Instance type check to make sure the
upgrade works.

So the impact here is more about when you retry a build, if use use the latest stable/kilo?

Omnibus stable/liberty fix

    There are currently 3 different blocking issues in stable/liberty due
    to library releases: webob 1.5, oslo.db 3.0.0, and
    oslo.versionedobjects 0.11.0. This is a squashed fix for all of them
    as none can land without the others.

Issue #1 - oslo.db

Add testresources used by oslo.db fixture

If we use oslo.db fixtures, we'll need the package or
the next version of oslo.db release will break us.

(Cherry-picked from 4bcc26487837b7ece7797f88622dea1b6d09bd94)

Closes-Bug: #1503501

Issue #2 - oslo.versionedobjects

Drop unused obj_to_primitive() override

    This was a band-aid override until o.vo gained the obj_relationships fix
    that this method overrides. That has been in place since o.vo 0.8.0, which
    means this is long since no longer necessary (and is actually blocking our
    ability to absorb bug fixes to this code in o.vo). Further, we no longer
    use this directly because we're doing backports based on version manifests,
    which means we no longer consult child_versions _or_ obj_relationships.

(cherry picked from commit 142f1d9cc4ace90956c665c40b1f78795f9f7e29)

Issue #3 - webob

Default ConvertedException code to 500

    webob 1.5.0 released on 10/11 has change f6c749011 which
    strictly enforces status codes in exceptions, and 0 is not
    a valid status code so tests fail.

Change the default to 500 to match the default in the parent
class in webob.

Revert "[libvirt] Move cleanup of imported files to imagebackend"

This reverts commit 9ba70756de326ffaa8be43acfde12cad04ed0af2

    The change introduced an UnboundLocalError if we fail to
    create the config_drive_image variable. Also, the original
    change didn't have any unit tests and came late in the
    liberty release so I don't really want to mess with fixing
    this given we need the fix in liberty-rc2.

    This fixes the InstanceV1 and InstanceListV1 backport code to properly
    initialize the temporary objects with a context. Without them, the
    objects are orphaned and can't do certain things.
    
    This should be backported to liberty

Ironic: Fix bad capacity reporting if instance_info is unset
    
    If node.instance_info is unset for a node that has an instance on it
    (for example, when upgrading Nova from before the patch that set these
    values on spawn), the Ironic driver reports 0 for both $resource and
    $resource_used. The resource tracker will correct $resource_used, and
    resources available will be reported as a negative number.
    
    Correct this by reporting the original value if instance_info is unset.

libvirt: check if ImageMeta.disk_format is set before accessing it
    
    Commit 4f43bbafa4bfc2ab149d5db4eb55320c1602658b changed
    blockinfo.get_root_info to access the disk_format attribute on the
    passed in image_meta (ImageMeta object) like an object, but if that
    attribute is not set you'll get an error.
    
    image_meta can be an empty object in the case of evacuate where
    image_ref is passed as None to the compute manager's rebuild_instance
    method in the case of evacuate, so image_meta defaults to {}. So when
    the ImageMeta object is created in LibvirtDriver.spawn, there is nothing
    in it.
    
    We have to check if the attribute is set before accessing it using
    obj_attr_is_set because the ImageMeta class does not include the
    NovaObjectDictCompat mixin, so we can't use
    image_meta.get('disk_format').

Add Pillow to test-requirements.txt
    
    Pillow isn't directly used by nova but it is used by
    sphinxcontrib-seqdiag.
    
    Add it to test-requirements as a work around to:

Cleanup of Translations
    
    In preparation for the release, do some cleanups for translations.
    
    Removes all po files that are partially translated. The translation
    team has decided to exclude files with less than 66 % of translated
    content. There is no content lost, all data is in the translation
    server, we just remove it from the repository.
    
    This change needs to be done manually since the automatic import does
    not handle some of these cases.

rebuild: Apply migration context before calling the driver
    
    In I0233f964d8f294f0ffd9edcb16b1aaf93486177f we made sure that we are
    properly using the data stashed in the migration context for resource
    tracking, however - we missed that we need to also apply it when passing
    data to the driver to do the spawn (or rebuild if implemented).
    
    This patch adds a context manager that helps us temporarily apply the
    migration context to an instance object, as we want to make sure that we
    don't save the new data before it's ready to be used by the resource
    tracker.

Correct Instance type check to work with InstanceV1
    
    When Liberty controller running with Kilo compute node, the Kilo
    compute node will send the InstanceV1 to the Liberty controller.
    Then all the checks like "isinstance(instance, objects.Instance)"
    on the Liberty controller won't works. Because objects.Instance
    pointed to objects.InstanceV2 now.
    
    This patch corrects all the Instance type check to make sure the
    upgrade works.

Fix MetricWeigher to use MonitorMetricList
    
    The commit I4dfbea27ce6c3eecc1a8658b1f9dc0feb2298705 changes
    'HostState.metrics' to 'objects.MonitorMetricList'. But MetricWeigher
    still use the old dictionary of 'host_manager.MetricItem'. This patch
    corrects the behavior of MetricWeigher with related tests, and delete
    unused MetricItem.

    Fix NoneType error when calling MetricsWeigher
    
    (this is a squashed commit since commit fd2b868 was buggy)
    Given that dict comprehensions don't allow to have None as a list, we had
    a problem with the Ironic gate-ironic-inspector-dsvm job because
    host_state.metrics was set to None by default.
    
    Adding a unittest to make sure we don't regress.
