Embodiment Construction

[0028] The following description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the invention is defined by the appended claims. For simplicity, the following embodiments are discussed with respect to the terminology and structure of virtual machines. However, the embodiments to be discussed next are not limited to these systems, but are applicable to other existing systems.

[0029] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the sam...

Abstract

A system, computer readable medium and method for merging a first virtual machine (98) and a second virtual machine (100) that runs on a same or different physical machines (90, 92). The method includes a step of receiving instructions for merging processes (P1) of the first virtual machine (98) with processes (P2) of the second virtual machine (100); a step of merging the first virtual machine (98) with the second virtual machine (100) onto a first physical machine (90); a step of merging an operating system (102) of the first virtual machine (98) with an operating system (104) of the second virtual machine (100) onto the first physical machine (90); and a step of maintaining active in the merged virtual machine (98) each process (P1, P2) that was active prior to merging the first and second virtual machines (98, 100).

Description

technical field [0001] The present invention generally relates to systems, software and methods, and more particularly, to mechanisms and techniques for splitting / merging virtual machines and their operating systems. Background technique [0002] Today, virtual machine technology has been used for a long time. A system virtual machine provides a complete system platform that supports the execution of a complete operating system (OS). A system virtual machine (sometimes called a hardware virtual machine) allows the underlying physical machine resources to be shared among different virtual machines, each running its own operating system. E.g, figure 1 A system 10 is shown comprising a computer 12 having a virtualization engine 14 and a plurality of virtual machines 16-20. The software layer that provides virtualization is called a virtual machine monitor or hypervisor 14 . Hypercontrollers can run on bare hardware or on top of an operating system. [0003] Some advantages...
