Display name is solely for UI purposes. In order to set the host name of a VM
to a desired value, you'll need to pass the name parameter(same as that of the
displayname). If the name parameter is not passed, the hostname would default
to VM-<UUID_of_VM>.

The metadata does not show the display name for local-hostname, for both
parameters I see the name value of the VM, the deploy was made via API and I
provided only the display_name, where the display name is "displayname01".
As you see here, public and local have the same value, from vm name.
{"vm_ip_address":"51.89.84.82","vm_metadata":[["userdata","user-data",null],
["metadata","service-offering","S-2"],["metadata","availability-zone","DE-00
1"],["metadata","local-ipv4","51.89.xx.xx"],["metadata","local-hostname","VM

],["metadata","instance-id","c8c113e0-3277-425e-882b-44937413fd4a"],["metada

Thank you,

If you are using the UI to create the VM, set the name of the VM - this
field sets the hostname and the display name. So you should see this value
in the local-hostname file in the VR metadata folder.
If you are using the API, explicitly set the name field.
Let us know if you see the desired name in the metadata after setting the
name parameter.
Thanks,

Hi Pearl,
I will test this when I upgrade to 4.18.x I'm waiting for 4.18.1.
Thank you,

Hi Cristian,
In addition, in 4.18 a new feature - managed User data was introduced. This
can be used to register userdata with custom parameters - here, the
hostname. And when deploying the VM, the custom parameters could be set to
the desired values. You could refer to
https://www.shapeblue.com/cloudstack-managed-user-data/ for more
information.
Thanks,
Pearl

Hi Cristian,
I'm not sure, but could you try user data (cloud-init data) when you deploy
a VM. In there, you'll have flexibility to set the hostname of the VM to
whatever you'd like.
Regards.

Subject: set display_name as hostname to instances
Hello,
Is there a method to set as hostnames to the instances the display name? I
did not see the display name in the metadata.
I am asking this because the display name allows any format, such as
fqdn.tld, and it does not matter if it's a duplicate or not.
Thank you,
Cristian
