After adding some POTATO debugs, it seems that meta_data generation does not actually happen for the instances I have tested.vif_vfs_trusted_supported = self._check_os_version(ROCKY, version)
LOG.info('POTATO -3 CHECKING IF WE HAVE DEVICE_METADATA| '+str(self.instance.device_metadata))
if self.instance.device_metadata is not None:
LOG.info('device_metadata is not None| '+str(self.instance.device_metadata))
for device in self.instance.device_metadata.devices:
device_metadata = {}
bus = 'none'In my logs2022-04-06 00:33:08.541 30 INFO nova.api.metadata.base [req-15612a39-649f-4598-b588-ebcceedd49b1 - - - - -] POTATO -3 CHECKING IF WE HAVE DEVICE_METADATA| Nonedevice_metadata = None so the condition is False so it skips all that code. It seems a bit strange, since None would mean there is nothing so let's add some data?I am not clear on how self.instance.device_metadata is expected to behave. I'll have to dig a little deeper.On Tue, Apr 5, 2022 at 7:58 PM Laurent Dumont <laurentfdumont@gmail.com> wrote:Trying to trace the code that I dont fully grasp :DWe start in nova/base.pyWe seem to generate a device array with a bunch of stuff insideif self._check_os_version(NEWTON_ONE, version):
metadata['devices'] = self._get_device_metadata(version)(but only if the version is higher than NEWTON_ONE? I dont think we generate the file every single time someone calls the API so it's probably at VM creation only?)Looking at the code for _get_device_metadataIt seems we try to build an array for Metadata specifically. It's not expected to be a full list of all the actual devices (ports + disks).I'll see if I add a tag to a port, does it now show up?On Tue, Apr 5, 2022 at 7:29 PM Laurent Dumont <laurentfdumont@gmail.com> wrote:Circling back on this, I see the same in my kolla-ansible + Ussuri.{"uuid": "a916a95d-3f9b-4e5e-9f64-894470742d8b", "hostname": "test-laurent.novalocal", "name": "test-laurent", "launch_index": 0, "availability_zone": "nova", "random_seed": "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", "project_id": "4db7dbf9961c4fc6a4589a5cb2ae3c9a", "devices": []}#Nothing in DevicesBut I see it in the network endpoint# curl http://169.254.169.254/openstack/2018-08-27/network_data.json

- How was it deployed?
