     Table. Required input fields for Virtual Server

     Notice

     • If the server name contains spaces or special characters (_), the OS hostname is set with the spaces and special characters (_) replaced by the special character (-). * Refer to this when setting the hostname of the OS.
       • Example: If the server name is ‘server name_01’, the OS hostname is set to ‘server-name-01’.
     • If you need to manage server names uniquely, create them by specifying different server names (Prefixes).
       • Because server numbers do not automatically increment based on the server name (prefix) at creation time, virtual servers with the same name can be created.
       • Example: If you first create two Virtual Servers using the server name (Prefix) ’test’, ’test-1’ and ’test-2’ are created. * Afterward, even if you create two virtual servers using the prefix ’test’ again, ’test-1’ and ’test-2’ are created.

  * Enter or select the required information in the **Additional Information** area.

4. Review the details and estimated billing amount generated in the Summary panel, and then click the Generate button.
5. When the popup window that notifies you of the creation opens, click the Confirm button.
   • After creation is complete, verify the created resource on the Virtual Server List page.
