We need to allow users to access VM details and console access – Create /etc/nova/policy.json with the following contents

{
    "os_compute_api:os-extended-server-attributes": "rule:admin_or_owner",
}

Update access rights

chmod 640 /etc/nova/policy.json
chgrp nova /etc/nova/policy.json

Restart nova-api service

systemctl restart nova-api
