Ok, got it, we need to tag the interface (or block device) on boot. I found how to tag using nova boot, is it possible to tag using openstack server create? Cheers, On 16.12.21 - 19:29, Arnaud Morin wrote:

Hey all,

How is filled the device_metadata in instance_extra db? It's empty for my instances.

It's supposed to be accessible then through metadata api, and contains at least network and block device info, but it's empty here.

Thanks for any hint!
