Thanks, Laurent. I tried it for both CEPH-backed VMs and ones with local disk, still, the devices array is empty

Network data curl shows alright

{"links": [{"id": "tapa.....", "vif_id": "ae....", "type": "bridge", "mtu": 1500, "ethernet_mac_address": "fa:......."}], "networks": [{"id": "network0", "type": "ipv4_dhcp", "link": "tap.....

Are you getting anything from the neutron endpoint?

Can you provide an "openstack server show $server_id" of the VM? I wonder if it's a case of boot from a volume VM missing that data. It would not explain why the port is not there though.

Hi All,

I am running into a strange issue with the metadata service. Per metadata-service manual, the devices attached to a VM should be visible in 

$ curl http://169.254.169.254/openstack/2018-08-27/meta_data.json

However, whenever i execute it from a VM , the devices array is empty and looks like this, any idea why ?

Thanks
