This paper is just a sharing of experiences that I have ever done. At the beginning of learning open source like Linux and OpenSolaris, I felt less with facilities such as a PC I have (had only one because ...: D). Though required to practice directly PCs else. From this arises the following questions:

- How do you let in one computer can be installed many operating systems, eg windows, linux, OpenSolaris?
- How do you let me be among those operating systems communicate with each other?
- Klo already finished making the system, how do I ngetesnya klo system has been successful / suskses?
- Then how do you get all three can be on / live all?
- And many other questions .... : D (Msh understand beljar nich ..)

From here I had a headache nyari effective solutions and certainly cheaper .. : D

With the help of Google's uncle, I finally found a solution that is effective and inexpensive fit my expectations .. ie virtualization techniques. Before I apply this virtualization technique I try to install the operating system directly to your hard drive so the computer starts klo I have to choose which to boot into nich? from here "cuman one operating system that could the road" ... in my opinion has not been able to answer my questions above.

Finally I apply the technique of virtualization to overcome the problems that I face this .. before going into the technical area, we try to understand what virtualization was sich?

- Wikipedia

virtualization (UK: virtualization), is a general term that refers to the abstraction of computer resources. Another definition is "a technique for hiding the physical characteristics of computing resources from how other systems, applications or users to interact with these resources. This includes creating a single resource (such as servers, an operating system, an application, or storage devices appear to function as multiple logical resources; or can also include definitions to create multiple physical resources (such as multiple storage devices or servers) appear as a single logical resource

Are simply the computer inside the computer, which in the implementation by the software. A virtual machine emulates the entire hardware system, from processor to network card, allowing different operating systems to run simultaneously. Each operating system software are on different partitions independently.

In sum might like this, we can install various operating systems on one computer, to do this well requires an emulator which is usually called a virtual machine. The point of this virtualization hardware resource sharing among virtual machines. Hardware one, but the operating system on the hardware that much. Physically, the number one, Hardisk his one, his RAM one, his mobo Logicalnya one but could be more than one.

Speaking of virtual machines, are now available of many kinds, to live choose according to taste ... (I like food aja ..: D)
- VMWare, made from VMware, inc .. www.vmware.com
- SUNXvm, virtual box, made from SUN Microsystems, www.sun.com
- Ldoms, vm for SPARC machines, made from SUN Microsystems, www.sun.com
- Microsoft Virtual PC, made from Microsoft, www.microsoft.com
- Xen, made from Red Hat, Inc., www.redhat.com
- Etc. ..
to the extent there are companies that make the built in to the operating system kernel, such distributions / operating systems for virtualization that is KVM (kernel based virtual machine, Redhat), ESXServer VMware (VMware, Inc.), Jeos (www.ubuntu.com)
how my friends? now everything is made easier with virtualization technology, so that you work hard and like to exercise .. : D

Step-step if want nginstall vmware, (ni favorite virtual machine ..)
1. Download VMware commercial ni lho .. .. so it must nyari crack (aka .. a real peasant pirate: D)
2. Install on Windows XP / Vista, klo been living on crack ..
3. Prepare CD Linux / OpenSolaris
4. Settings in VMware CDROM to load from CD
5. Click Start ... (read klo wuff doang so dizzy, must dipraktekin ..: D)

If you've installed the operating system that we need, we enable remote computernya features such as ssh, telnet, ftp, etc ... Now I've managed to run different operating systems in one PC, and remote-testing machine
