INTRODUCTION OF VIRTUAL MACHINE WHAT IS IT?
04/26/09
In computer science, a virtual machine (VM) is a software implementation of a machine (computer) that executes programs like a real machine. A virtual machine takes the layered approach to its logical conclusion. It treats hardware and the operating system kernel as though they were all hardware A virtual machine provides an interface identical to the underlying bare hardware The operating system creates the illusion of multiple processes, each executing on its own processor with its own (virtual) memory 3

The virtual-machine concept provides complete protection of system resources since each virtual machine is isolated from all other virtual machines. This isolation, however, permits no direct sharing of resources. A virtual-machine system is a perfect vehicle for operating-systems research and development. System development is done on the virtual machine, instead of on a physical machine and so does not disrupt normal system operation.
5
THE ORIGIN
Computer systems are constructed of the three major components :hardware, the operating system, and application programs. The three major system components are stacked on one another to reflect the direct interaction that takes place.
A computer system consisting of Hardware that implements an Instruction Set Architecture (ISA), an Operating System, and a set of Application programs.

7
THE SOLUTION One type of virtual machine (VM) is virtualizing software is placed between the underlying machine and conventional software.
Virtualizing software translates the hardware ISA so that conventional software “sees” a different ISA from the one supported by hardware.

A system virtual machine provides a complete system environment. This environment can support multiple user processes, includes a file system, provides the processes with access to I/O devices, and, on the desktop, it supports a GUI.
Windows system supported as guest virtual machine running on a Linux/x86 host platform.

VIRTUAL MACHINE ARCHITECTURE 04/26/09

SYSTEM VIRTUAL MACHINE System Virtual Machine is capable of supporting an OS along with potentially many user processes.

IMPLEMENTATION
04/26/09
In Figure 0-10, the “classic” VM, the VMM is placed on “bare” hardware. The VMM runs in the most highly privileged mode, while all the guests run with lesser privileges. Then, the VMM can intercept and implement all the guest OS's actions that interact with hardware resources
12
CONTINUE
04/26/09
An alternative system VMM implementation builds virtualizing software on top of an existing host operating system – resulting in what is called a hosted VM With a hosted VM, the installation process is similar to installing a typical application program Furthermore, virtualizing software can rely on the host OS to provide device drivers and other lower-level services; they don’t have to be done by the VMM
13
EMULATION Execute binaries compiled to a different instructio n set than that executed by the host’s hardware. This process helps to converts the guest system ISA operation equivalent to host OS. So, it allows software application and operating system written for guest ISA, to be run in host OS ISA.
04/26/09
14
OPTIMIZATION VMs designed to enable innovative ISAs and/or hardware implementations for improved performa nce, power efficiency, etc. Similar hardware virtualization is common for microprocessors, such as Pentium IV. Software VM is part of the hardware design

MULTIPROGRAMMING
Conventional multiprogramming provides each user process with the illusion of having a complete machine to itself. Each process is given its own address space and is given access to a file structure. The operating system timeshares the hardware and manages underlying resources to make this possible.

VIRTUALIZATION Virtualization constructs an isomorphism that maps a virtual guest system to a real host. It can be thought of a partitioning where a single physical server is sliced into multiple small partitions.

ADVANTAGES
The only advantage is that we don't have to buy two computers, and we don't have to stand up from one computer and walk to the other Increase the hardware utilization Decrease the capital and operating cost by sharing in number of VM High availability and Secure VM can use from anywhere in the intranet

DISADVANTAGES

The disadvantages are that they are really slow, and not quite as stable. Setting up networking can sometimes be a pain (but is solvable)

TUTORIAL : HOW TO INSTALL
Installing the Windows 7 Beta with Virtual PC 2007 SP1 Download and install Virtual PC from
04/26/09
http://www.microsoft.com/downloads/details.aspx?FamilyId=28C9 Download windows 7 beta here but only 32-bit edition because virtual PC 2007 only support 32-bit guest OS
http://www.microsoft.com/windows/windows-7/beta-download.asp
22
1. Open Virtual PC (Start –> Programs –> Microsoft Virtual PC) and click New… to launch the New Virtual Machine Wizard. Click Next. 04/26/09
2. Ensure that “Create a virtual machine” is selected and click Next. 3. Provide a name and location for your virtual machine and click Next. I suggest saving this in the same location that you will create your VHD file (step 6). 4. The next dialog prompts you for the operating system you will be running. Since Virtual PC 2007 SP1 isn’t familiar with Windows 7, just23 select Windows Vista from this list. Click Next.
04/26/09
5. The next dialog asks you how much RAM you would like to assign to your virtual machine. This is always a balancing act to determine the right amount of RAM to allocate to your virtual machine and how much to allow your host operating system to utilize, but as a rule of thumb I suggest allocating 50% of your physical RAM to your virtual machine. For example, if you have 1GB of RAM in your computer, try assigning 512MB to the virtual machine. Click Next when you have allocated your RAM. 6. Select “A new virtual hard disk” and click Next. 7. Give your new virtual hard disk a name and location. I suggest using a location that has at least 16GB of disk space available. An external (e.g. USB2) hard drive works well for this purpose since it’s portable and it allows your computer to load balance disk IO between your system drive and the external drive. For “Virtual hard disk size” leave the default value and click Next when ready. 8. Click Finnish
24
10. Your virtual machine should now boot up and look for an operating system to boot to. Since you haven’t installed an operating system yet, it will eventually time out with the message below. It might take a minute or two to time out while it looks for a network device to boot off of, so be patient.
04/26/09
9. Your Virtual PC Console should now have a new entry representing your new virtual machine. Highlight this entry and click Start.
25
12. Now simply select your virtual machine and press <Enter>. If you’ve done everything right so far, then your virtual machine should now launch the Windows 7 Beta setup!
04/26/09
11. Now from the top of the Virtual PC 2007 window click on CD – > Capture ISO Image and select the Windows 7 beta ISO image you downloaded in step 2. It should be called 7000.0.0812121400_client_en-us_Ultimate-GB1CULFRE_EN_DVD.iso. This will mount the ISO image as a DVD drive available to your virtual machine.
26
04/26/09
13. The first few screens should be self-explanatory. When asked what type of installation you want, be sure to choose “Custom (advanced)” since you are not upgrading from a prior version of Windows.
14. The rest of the setup should be the same as any OS, but when you use your mouse to control your virtual Windows 7 OS, you won’t be able to move your cursor outside of the virtual machine. To release the mouse 27 press the key
CONGRATULATIONS!!!!!! 04/26/09
You have installed your first virtual windows 7
