Abstract
An arrangement for facilitating remote booting in diskless client systems as just described. To this end, there is broadly contemplated herein the employment of a hypervisor that can freely accommodate a variety of booting arrangements for a given OS. This then ensures that few if any modifications, especially costly ones, would need to be made to the OS to ensure greater versatility.
Claims20
A system comprising:
- a client;
- the client comprising a processor that first loads a hypervisor from a memory and thereafter enables an operating system configured to use local storage during boot up to remotely boot;
- wherein the hypervisor captures communication actions directed to local storage and one or more LAN accesses from the operating system configured to use local storage during boot up and diverts the communication actions directed to local storage to a remote storage device;
- wherein the one or more LAN accesses are treated differently than normal network traffic.
A method comprising:
- loading a hypervisor at a client from a memory;
- and
- remotely booting an operating system configured to use local storage during boot up at the client after loading the hypervisor;
- wherein the hypervisor is employed to:
- capture communication actions directed to local storage and one or more LAN accesses from the operating system configured to use local storage during boot up;
- and
- divert the communication actions directed to local storage to a remote storage device;
- wherein the one or more LAN accesses are treated differently than normal network traffic.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform acts comprising:
- loading a hypervisor at a client from a memory;
- and
- remotely booting an operating system configured to use local storage during boot up at the client after loading the hypervisor;
- wherein the hypervisor is employed to:
- capture communication actions directed to local storage and one or more LAN accesses from the operating system configured to use local storage during boot up;
- and
- divert the communication actions directed to local storage to a remote storage device;
- wherein the one or more LAN accesses are treated differently than normal network traffic.
