VMware, Inc. is a provider of virtualization software.The company was founded in 1998 and is based in Palo Alto, California.The Company is majority owned by EMC Corporation .VMware's desktop software runs on Microsoft Windows, Linux, and Mac OS X.VMware's enterprise software, VMware ESX Server, runs directly on server hardware without requiring an additional underlying operating system.Founded in 1998 , this enterprise today produces best virtualisation solution for desktops and servers.VMware software provides a completely virtualized set of hardware to the guest operating system.VMware software virtualizes the hardware for a video adapter, a network adapter, and hard disk adapters.The host provides pass-through drivers for guest USB, serial, and parallel devices.
In this way, VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest.
In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension.
Alternately, for enterprise servers, a feature called VMotion allows the migration of operational guest virtual machines between similar but separate hardware hosts sharing the same storage.
Each of these transitions is completely transparent to any users on the virtual machine at the time it is being migrated.VMware's products use the CPU to run code directly whenever possible .
When direct execution cannot operate, such as with kernel-level and real-mode code, VMware products re-write the code dynamically, a process VMware calls "binary translation" or BT. The translated code gets stored in spare memory, typically at the end of the address space, which segmentation mechanisms can protect and make invisible. For these reasons, VMware operates dramatically faster than emulators, running at more than 80% of the speed that the virtual guest operating-system would run directly on the same hardware.

Basically for desktop theere are 5 products of VMware :
*VMware Fusion
*VMware Workstation
*VMware View
*VMware Player
*VMware ACE

I have been looking forward for a replacement of Vitualbox OSE . This thing started our quest for finding a Visualization application to fulfill the needs with an easy-to-use procedure. I found KVM in Add/remove while i was looking for something alike YaVM - Yet another Virtual Machine (An application developed for openSUSE in 2006 to serve as basic virtual machine that comes with the os preinstalled). Xen , the geeky Virtual machine by SUSE linux enterprise is a virtualisation powerhouse. While Xen offers quite complex procedure requiring you to boot a patched Xen kernel to create and run a Virtual machine - KVM is a loadable module which runs with the OS's default kernel module. The only thing it requires is that your processor should have the architecture to support virtualisation .

For this type:

kvm

in the terminal and see the result:

QEMU PC emulator version 0.9.1 (kvm-84), Copyright (c) 2003-2008 Fabrice Bellard
usage: qemu [options] [disk_image]

If you see the above message, then you should be smiling as you are green to go for virtualisation with your hardware.

But if your CPU does not, in fact support Hardware virutalization, you will get output such as the following:

$ kvm
Could not initialize KVM, will disable KVM support
Ubuntu does not support running KVM without hardware acceleration. Sorry.

So lets start our work with Virtualisation weapons at hand. First, head on over to the KVM HOME PAGE :

http://www.linux-kvm.org/page/Main_Page

Best feature of KVM is that it is part of the OS and is not dependent upon a 3rd party vendor . Also, it’s very easy to maintain as you update your system, and load new kernel revisions, as the module will not break like VirtualBox and VMware solutions would. Also, it’s far less problematic to manage than Xen, which is entirely unsuitable for a desktop system IMO :P . KVM really is more of a direct competitor to Xen than to a workstation solution like VirtualBox or VMware workstation, and has some very powerful features, I will never tap into here on my home system. By design however, it’s far less intrusive on a standard Linux desktop than Xen.

Now we have our kernel module working properly and rest everything in place so must get back to bussiness :D. I will use Lubuntu for the testing purpose coz its my personnel favourite and it very light too.

Follow these steps to set up your virtual Machine :-

Step I : Launch :- Goto Applications>System tools and start KVM . Then choose the virtualisaton method to full virtualisation if your processor supports that feature.





Step II :Installation Method :- Now choose the media from which the OS is to be installed to the machine . Also chose the OS type and its Variant .




Step III : Installation Media : Select he ISO image location (whether from External drive or already present image from HDD) .



Step IV :Allocating Space:- Choose the disk space you wnt to allocate to the machine's Virtual Hard drive. Allocate space wisely for stability issues .Then select to allocate the whole virtual hard disk to the machine .


Note: If you dont allocate the whole virtual hdd to the machine , then the machine will allocate space for itself while it is running and if the space in that partition goes out , the the data in the virtual machine is likely to get corrupted. You can allocate additional space like network drives etc to your virtual drive.

Step V : Memory &  CPU allocation :- Allocate RAM for your machine which it wil be able to utilize to max. You have to allocate RAM for peak run and startup diffrently. Do it generously for proper running of he host and virtual machine . Eg: i have 2 gb RAM and i allocated 750 mb to the machine to max and for start-up , i gave it 512 mb. You can change the se settings in the hardware section og the gui while running the machine.



Step VI : Finishing Job :- Check your preferences and Click finish & let the magic happen. The installation os a virtual OS is totally same as installing a regular OS. So, now we are done with it .



Obviously , KVM is much more capable than we discussed just now. We were just able to do the basics, rest you can try on your own after installing the application.


Happy Virtualistion !!!
