Abstract: Systems and methods are described for providing a Graphical User Interface (“GUI”) for applying an existing image to a server cluster. The existing image can come from a host known or unknown to a system. For a known host, using the GUI a user can select a host from a list of known hosts. A server can import an image file for the selected host and create a server cluster with the image file. For an unknown host, using the GUI the user can input an address and access credentials for the unknown host. The server can use the address and access credentials to import an image file and create a server cluster. Using the GUI, the user can also apply an existing image to hosts in an existing server cluster or use an existing image to add new hosts to a cluster.
