     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to information handling systems and more particularly to a modular virtual machine server. 
         [0004]    2. Description of the Related Art 
         [0005]    As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems. 
         [0006]    One issue relating to information handling systems is often businesses such as small businesses lack the skills manage a complex information technology (IT) infrastructure. Additionally, businesses such as small business are often space constrained to have many large server type information handling systems. Many businesses also would prefer to start with a smaller IT infrastructure but wish to preserve the ability to expand the IT infrastructure as the business grows. 
         [0007]    Accordingly, it would be desirable to provide an easily manageable and expandable array of server based functions to businesses or consumers with limited or no IT capabilities. 
       SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION 
       [0018]    Referring briefly to  FIG. 1 , a system block diagram of an information handling system  100  is shown. The information handling system  100  includes a processor  102 , input/output (I/O) devices  104 , such as a display, a keyboard, a mouse, and associated controllers, a memory  106  including volatile memory such as random access memory (RAM) and non-volatile memory such as a hard disk and drive, and other storage devices  108 , such as an optical disk and drive and other memory devices, and various other subsystems  110 , all interconnected via one or more buses  112 . One example of another storage device  108  is a virtual appliance memory device such as a virtual appliance USB key  120 . 
         [0019]    The virtual appliance USB key  120  can include one or a plurality of virtual appliances. Each virtual appliance is a self-contained virtual machine that implements a business solution (including an operating system (OS), and application and a default configuration). Examples of self-contained virtual machines can include a voice over internet protocol (VoIP) server, an email server, a digital signage solution, a surveillance tool, a background music server, a business accounting solution, a point of sale (POS) solution. Because the virtual machines are self-contained and isolated using virtualization technology, each solution can be preconfigured and ready to use, without a customer having to install and configure the solution. 
         [0020]    Each of the virtual appliances is installed on the information handling system  100  via a respective virtual appliance USB key  120 . Using a virtual appliance USB key  120  not only simplifies an initial installation, but also subsequent need to move the virtual machine if the capacity of the server is exceeded.  FIG. 2  shows the architecture diagram of the virtual server. 
         [0021]    For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components. 
         [0022]    Referring to  FIG. 2 , a system block diagram of an IT infrastructure architecture  200  is shown. More specifically, a server type information handling system  210  executes a virtual machine monitor application  212 . The IT infrastructure architecture  200  also includes a service operation system  214  and a management web server  218  which are executed by the server  210 . 
         [0023]    One or more virtual appliance USB keys  120   a,    120   b,  and/or  120   c  may be coupled to the server  210 . Each of the USB keys  120  allow a self contained virtual appliance  220  to be installed on the server  210 . In certain embodiments, a digital certificate of authenticity (COA) is included with each virtual appliance  220 . The COA is checked by the virtual server  210  before the appliance is installed onto the virtual server  210 . 
         [0024]    A data structure with computing resource requirements is included with each virtual appliance on the USB key. These include CPU requirements, memory requirements, storage requirements, and network bandwidth requirements. Before a virtual appliance is installed, the virtual server ensures that it has enough capacity to host the appliance. The server also contains a resource meter (which may be located on a panel of the server) to represent current resource capacity and remaining resource capacity to simplify capacity planning. 
         [0025]    Referring to  FIG. 3 , a flow chart of the operation of a virtual appliance installation module  300  is shown. More specifically, when the server  210  detects a USB key insertion event at step  310 , the virtual server  210  determines whether the USB key is an authorized virtual appliance (VA) key (e.g., does the VA key correspond to a particular business) at step  312 . If the key is not an authorized key, then the virtual appliance installation operation exits. If the key is an authorized key, then the virtual server  210  analyzes the digital certificate of authenticity at step  314  and determines whether the virtual appliance includes a valid license at step  316 . If the license is not valid, then the virtual appliance installation operation launches a web browser to access a virtual appliance licensing set at step  320 . 
         [0026]    If the license is valid, then the virtual appliance installation operation accesses the resources of the server at step  318 . The virtual appliance installation operation then determines whether the server  210  is over capacity at step  332  based upon the available resources of the server  210  as well as the resources needed by the virtual appliance. If the server  210  is over capacity then the virtual appliance installation operation warns the user at step  334 . If the resource of the virtual server is exceeded (e.g., as determined by step  332 ), the user is warned by a front panel indicator of this condition. The user may proceed with a number of options. The user can ignore the warning and leave the USB key in the system, in which case the system performance may degrade. Alternately, the user may remove the USB key from the system and insert the key into another system with more system resource capacity. 
         [0027]    If the server  210  is not over capacity then the virtual appliance installation operation caches the virtual appliance to local storage or synchronizes the virtual appliance with a server copy at step  340 . Next, the virtual appliance installation operation launches or resumes operation of the virtual appliance at step  342 . 
         [0028]    Referring to  FIG. 4 , a flow chart of the operation of a virtual appliance removal module  400  is shown. More specifically, when the server  210  detects a USB key removal event at step  410 , the virtual server  210  suspends execution of the virtual appliance that corresponds to the removed key at step  420  and generates a notification of the suspended virtual appliance at step  422 . The front panel of the virtual machine server also indicates the removal of the key. 
         [0029]    Referring to  FIG. 5 , a conceptual view of a panel  500  of a modular virtual machine server type information handling system is shown. More specifically, the panel  500  includes a plurality of USB connections  510 . Each USB connection includes a corresponding connection indication  520 . The USB connection indication  520  can include indicia (e.g., a color indication) of whether a virtual appliance is installed and executing on the server  210 . 
         [0030]    The present invention is well adapted to attain the advantages mentioned as well as others inherent therein. While the present invention has been depicted, described, and is defined by reference to particular embodiments of the invention, such references do not imply a limitation on the invention, and no such limitation is to be inferred. The invention is capable of considerable modification, alteration, and equivalents in form and function, as will occur to those ordinarily skilled in the pertinent arts. The depicted and described embodiments are examples only, and are not exhaustive of the scope of the invention. 
         [0031]    For example, the virtual appliance memory device  120  may function as a license and resource management token and not necessarily as a storage device for the virtual appliance. 
         [0032]    For example, the above-discussed embodiments include software modules that perform certain tasks. The software modules discussed herein may include script, batch, or other executable files. The software modules may be stored on a machine-readable or computer-readable storage medium such as a disk drive. Storage devices used for storing software modules in accordance with an embodiment of the invention may be magnetic floppy disks, hard disks, or optical discs such as CD-ROMs or CD-Rs, for example. A storage device used for storing firmware or hardware modules in accordance with an embodiment of the invention may also include a semiconductor-based memory, which may be permanently, removably, or remotely coupled to a microprocessor/memory system. Thus, the modules may be stored within a computer system memory to configure the computer system to perform the functions of the module. Other new and various types of computer-readable storage media may be used to store the modules discussed herein. Additionally, those skilled in the art will recognize that the separation of functionality into modules is for illustrative purposes. Alternative embodiments may merge the functionality of multiple modules into a single module or may impose an alternate decomposition of functionality of modules. For example, a software module for calling sub-modules may be decomposed so that each sub-module performs its function and passes control directly to another sub-module. 
         [0033]    Consequently, the invention is intended to be limited only by the spirit and scope of the appended claims, giving full cognizance to equivalents in all respects.
