How To rename an Instance/Server in OpenStack

Posted on 104 views

How can I rename an VM, instance or server in OpenStack?. Once you create an instance in OpenStack, you can modify its name in running state. This is true if the service running in the VM is changed, and the name needs to be updated to reflect the same.

Modifying an Instance/VM name in OpenStack can be done from the CLI or Horizon dashboard.

Change / Rename Instance in OpenStack CLI

Get the current instance name:

$ openstack server list
+--------------------------------------+-------------------+---------+-----------------------------------+-----------+-----------+
| ID                                   | Name              | Status  | Networks                          | Image     | Flavor    |
+--------------------------------------+-------------------+---------+-----------------------------------+-----------+-----------+
| d3ae9771-3a95-466d-a1ef-656ee2bb8456 | fed30             | ACTIVE  | private=10.10.1.191               | Fedora-31 | m1.small  |
+--------------------------------------+-------------------+---------+-----------------------------------+-----------+-----------+

Set the new instance name:

$ openstack server set --name fed31  d3ae9771-3a95-466d-a1ef-656ee2bb8456

Confirm that the new name is set:

$ openstack server list
+--------------------------------------+-------------------+---------+-----------------------------------+-----------+-----------+
| ID                                   | Name              | Status  | Networks                          | Image     | Flavor    |
+--------------------------------------+-------------------+---------+-----------------------------------+-----------+-----------+
| d3ae9771-3a95-466d-a1ef-656ee2bb8456 | fed31             | ACTIVE  | private=10.10.1.191               | Fedora-31 | m1.small  |
+--------------------------------------+-------------------+---------+-----------------------------------+-----------+-----------+
