Hi everyone, I tried a little today. $ nova meta my_instance set hostname=new_hostname I didn't get any errors. Nothing in the instance (curl http://169.254.169.254/latest/meta-data/hostname) even after reboot and nothing in the instance db record. Here are the nova-api trace, seems to be ok: 2012-08-07 15:18:58 INFO nova.api.openstack.wsgi [req-c8bf2011-933b-4d6a-b28c-48063252fbf1 359076e3189b4658a4dd1b83d6313cc9 5172f50226f647ebb03ca4e4e82d056d] POST http://172.17.1.2:8774/v2/5172f50226f647ebb03ca4e4e82d056d/servers/4e1c4652-199c-4160-9a73-2eddcf4cd21f/action 2012-08-07 15:18:59 INFO nova.api.openstack.wsgi [req-c8bf2011-933b-4d6a-b28c-48063252fbf1 359076e3189b4658a4dd1b83d6313cc9 5172f50226f647ebb03ca4e4e82d056d] http://172.17.1.2:8774/v2/5172f50226f647ebb03ca4e4e82d056d/servers/4e1c4652-199c-4160-9a73-2eddcf4cd21f/actionreturned with HTTP 200 Did I miss something? Last question, is there a way to update the metadata of a running instance. I mean instead of updating the db record... For example re-injecting a SSH key?
