Increasingly is in "fashion" the use of virtual machines, either for development or for presentations. A virtual machine (Virtual Machine) is the simulation of an operating system, only through software, ie we are running another operating system within which we are running. This process is called virtualization. This virtualization allows sharing the resources of the host computer running different virtual machines, thus simulating multiple computers.

The use of virtual machines has several advantages, for example, can create a virtual machine for each development environment (for ex.:. Net and php), we can test new operating systems easily, we can move the virtual machines between the pcs quickly, we have a development environment, pre prepared quickly, etc ... The benefits are immense, but there are also some disadvantages, obviously. The use of virtual machines requires a computer with resources above the recommended, since these will be shared with multiple virtual machines, especially the RAM, the CPU and Disk. The performance in a virtual machine is naturally inferior to that of a normal computer.

To get an idea with the minimum resources required to run a virtual machine with the various Microsoft operating systems, see the following table:

These are the minimum requirements that the virtual machines need. Therefore, the better for the host computer, can share more resources with the virtual machines, and get better performance, because as we all know, Windows Vista with 512 MB of RAM is going ...
For the CPU, the faster better. It will be shared with the virtual machines that are running.

To make the virtualization there are essentially two programs:

• Microsoft Virtual PC 2007 (free)
• VMWare (paid)

In this tutorial we will use the Virtual PC 2007. Can download this software through the following url:

http://www.microsoft.com/downloads/details.aspx?FamilyId=04D26402-3199-48A3-AFA2-2DC0B40A73B6&displaylang=en

There are two versions available, a 32-bit and one 64-bit, both with approximately 30 MB.

Installing Virtual PC 2007 is simple, why is not addressed in this tutorial. No doubt leave a comment.

We are then setting up the virtual machine.

• Open the Virtual PC 2007 and click on "New."

• In the window that opens, click on "Next"

• In this screen we have three options available. To create a new virtual machine from scratch, chose the first option and click "Next."

• On the next screen choose the name and location where you want to save the configuration of the virtual machine created and click "Next."

• Then we will choose which operating system we will install the virtual machine that we are creating. In this tutorial we will choose the Windows XP and click "Next." If you create a virtual machine to another operating system, should choose the option that best fit the system that want to install.

• On the next screen, we have chance to choose which memory you want to share with the virtual machine. For Windows XP the option that comes pre-set is 128 MB, however, should increase this value, choosing the option "Adjusting the RAM" and moving the slider or by entering the value in the box on the right. For this tutorial choose 512 MB. This value can be changed after the virtual machine is created.

• Now select the disk of the virtual machine. As we are preparing a virtual machine for installing a new operating system to choose "A new virtual hard disk".

• On the next screen, we set the size, name and location of the virtual machine disk. This file. HDV (virtual hard disk) will be saved all the files in the virtual machine. For the tutorial, select a disc with 20000MB (approx. 20 GB). Virtual PC USA a system of dynamic disk, or even 20GB of terms assigned to the disk, not once occupied 20 GB on the disk of the host computer, the information is increased as is necessary, despite the virtual machine always see the disk with 20 GB. Therefore, it is preferable to define a disc more than minor, because if the virtual machine's disk is full, it is very difficult to increase their size.

• We reach the final configuration of the virtual machine. In this screen we have the summary of the settings chosen. Just click "Finish".

• We already have available to virtual machine in Virtual PC 2007. If you click "Start" will start the machine now, but without operating system.

• At startup, the virtual machine needs to make some settings that may take several minutes.

• Then it waits to make a boot cd with the new operating system. But this is for the next tutorial.

In the second tutorial in this series, explaining how to install the operating system in virtual machine you just created:
