Web Application to Start a Second Level System Running Under a Hypervisor

A method is needed to automate the start of a computer operating system running under a hypervisor. Currently, the computer operator or systems programmer uses a terminal emulator to perform this function.

With the advent of virtualized systems, it is no longer efficient for the end user to wait for a computer operator or a systems programmer to start the operating system. In addition, the computer operators and systems programmers no longer need to be tied to a particular device or emulator to perform such a routine task for their customers. This solution permits a user to start a second level guest after possibly altering rudimentary startup parameters using a web application that eliminates any hardware device from virtually anywhere.

At its core, this solution uses a front-end web application to:

 Authenticate the user

 Identify the systems with which the user is entitled to work

 Permit the user to select a guest image from that subset

 Select a pre-determined number of startup parameters to be modified

 Submit the system start request

The request is channeled to the hypervisor waiting for such requests. The machine reads the request from the reader queue, modifies the files necessary for the start, and issues the appropriate start command. Tasks required to run after the system startup may also be submitted to the second level guest operator's console as part of the startup process. The end user is notified with an email.

Computer Operators and Systems Programmers may also take advantage of invoking standard user-requested starts of the operating system by simply being connected to a web-based device vs. a workstation with a terminal or emulator.

The user invokes a web page. In its current implementation, it confirms the user's identity via a check against a Lightweight Directory Access Protocol (LDAP) database. Once the user is authenticated, the system displays a list of second level g...
