VMWare is a software for the
virtual machine (virtual machine). Its function is to run many operating
systems in one hardware and to run applications that are intended for other
operating systems. Another function is to learn an operating system is best
when the learning process or when the operating system development process.
The term Virtual Machine (VM)
itself began to be introduced by IBM as the operating system launched in 1965
mainframenya's. Introduced for S/370 and S/390 systems and is referred to as
our operating system VM / ESA. So often creates confusion between the naming of
a product or naming mechanism. Many people who called, even has a virtual
machine mechanism but in a non-IBM systems, it is not called the Virtual
Machine. In this explanation, be concluded that the term virtual machine is a
type of virtualization mechanism of a machine on other machines. So it's not
the type of products from one vendor with the name of the Virtual Machine.
VMWare allows bebarapa operating
system running on a single PC machine simultaneously. This can be done without
re-partition and reboot. In the virtual machine provided by the operating
system will run as expected. In this way the user can boot an operating system
(eg Linux) as the host operating system (the host operating system) and then
run other operating systems such as MS Windows. Operating system which runs on
the host operating system known as a house guest operating system (guest
operating system)
There are three types of VMWare,
namely:
1. VMWare
Workstation is virtual machine software for compatible with Intel x86
computers. This software allows users to create one or more virtual machines
and run them simultaneously. Each guest virtual machine can run its own
operating system like Linux, Windows, BSD, and others. But this software can
not run virtual machines created by other VMware products.
2.
VMWare Server actually has a working system with
VMWare Workstation. But compared with VMWare Workstation, VMWare Server has the
advantage that it can run virtual machines created by other VMware products.
VMWare Server can also run virtual machines created by Microsoft Virtual PC.
3.
VMWare
Player is a software used to run virtual machines created by other VMware
products. But this software can not mebuat own virtual machine.
However, VMWare does not support
the Fire Wire, also does not provide support such as USB 2.0 devices but VMWare
will make USB 2.0 devices on the host operating system on the guest operating
system is detected as USB 1.1 devices. VMWare is really just providing hardware
3D acceleration because it is experimental.
Pros and Cons of VMWare:
1.
Why use VMWare?
·
One good reason to use VMWare is when we are
required to use them. For example, I as a lecturer on network connections and
security by using various operating systems, which requires that I use a laptop
with a variety of operating systems.
·
VMWare will create a virtual machine that you
can configure according to your needs and does not rely on the existing
hardware on your computer. For example, he is by default a 4 GByte file on the
hard drive to emulate drives on the virtual machine. By the virtual machine,
this file looks like a SCSI drive, which in fact just a file on the IDE drive.
Also by default, it uses an IDE CD drive as ... an IDE CD drive. Though you can
tell the virtual machine to use it as a SCSI drive, or create a CD-ROM ISO
image as a drive with a CD in it (eg for installation). You can use the actual
hardware you do not have, such as tape drives.
·
You also can have multiple virtual machines
running at the same time, and create a local network on your computer with a
variety of different operating systems. It's good to try a new operating system
without repartitionning (wiping it back out just a click away); see how the new
operating system that integrates with your network that already exists; demonstrate
to people how many operating systems interconnected and integrated with a
projector.
2.
Why not use VMWare?
·
Speed. However, we are sharing a CPU between two
or more operating systems.Although this problem becomes serious if we run the
usual programs on only one system at a time. One thing that is nice on a SMP
system to run VMWare using one CPU to each virtual machine ... although it is
impossible to do without redesigning the entire host operating system kernel.
·
Speed once again. You need plenty of RAM to run
at normal speed. Try to have at least 128 MByte per operating system, or be
prepared for intensive swapping. This may be a problem on a laptop (remember
that the hard drive on a laptop is not built for intensive use). Try not to use
the swap virtual machine's system.
·
Speed, for the third time. All the peripherals
(drives, network cards) are divided for each virtual machine. For example, on a
computer with two virtual machines running and with a lot of luck, each system
gets a fair share (one-third - remember the host system!) Of bandwidth. The end
result can be much lower, mainly depending on the design and efficiency of the
host operating system.
Basically, VMWare is not an
emulator, because it does not emulate the CPU and hardware in a virtual
machine, but only allow other operating systems run in parallel with the
operating system that has been running. Each virtual machine can have its own
IP address (if the machine is on a network), and users can take it as a
separate machine.Virtual machine has access to the network through a
proprietary protocol bridging VMWare but only if your network card has been
enabled by the host system. He could use a static IP address or get a dynamic
address from the DHCP server on your network. You can then connect to a server
running on a virtual machine from the virtual machine itself, from other
computers on your network, or even from the host computer via an external
network address on a virtual machine. Note that VMWare gives the host system
and virtual machines in subnetwork 192.168.19.0/24 and 192.168.199.0/24 for
bridging protocol so that you can not use it for your connection.
