# Hosts


On the **Hosts** page, you can view a list of host machines (either cloud or on-premises) you have installed Amazon DCV servers configured with Amazon DCV Session Manager.

Before your users can connect to a Amazon DCV session, you must have hosts available for users to create sessions on. You can't spin up hosts, install Amazon DCV servers on hosts, or configure them with the Amazon DCV Session Manager from the console. For more information about installing Amazon DCV servers, see [Installing the Amazon DCV server](https://docs.aws.amazon.com/dcv/latest/adminguide/setting-up-installing.html).

You can configure the visible fields in the top navigation bar by selecting the gear icon. To view more details in a split panel view, select a session and then click the caret (**^**) icon at the bottom-right corner of the page.
