I'm wondering if there is any method that could check the error message of an instance whose status is "ERROR"? Like from openstack cli, "openstack server show server_name", if the server is in "ERROR" status, this will return a field "fault" with a message shows the error. I tried the compute service get_server and find_server, but neither of them show the error messages of an instance.
Hi, it looks like currently the sdk doesn't have the 'fault' field in the Server model [1] so AFAICT you can't get the fault message out-of-the-box. A patch upstream will be needed to add it.
This can be hacked around by, for example:
import openstack from openstack.compute.v2 import server from openstack import resource
class MyServer(server.Server): fault = resource.Body('fault', type=dict)
conn = openstack.connect(cloud='devstack') s = conn.compute._get(MyServer, '9282db95-801f-4f43-90fb-e86d9bfb6785') s.fault {'code': 500, 'created': '2021-09-17T02:23:16Z', 'message': 'No valid host was found. '}
