All about Virtualization (Part 1)

If you’re a student  or an IT guy who need to work on virtual machines then this article is probably for you.  There are favourite software among regular virtual software users. They are ,

2.      VMware workstation Pro

As I was doing some research on the internet about VMware , I wish to explain about VMware software packages.  We know that the VMware is not an open sours  application software package. But the people who knows the advantages of having a VMware workstation software always choose that. So they will try to buy that or torrent that.

VMware workstation is a popular windows based virtual machine running software that available for both Windows and Linux. This supports lots of operating systems. This also can run second desktop with different settings, tools & network settings. This software can isolates the each and every virtual environment. Another advantage is the user can create the number of clones as his wish. This also supports for building up virtual networks. VMware workstation also used by the IT specialists to virtualize the physically running computers in case of emergency.  But when we are running the multiple virtual computers the keyboard, mouse and the other input & output devices we have to use the same for every OS.

Now we are entering the main topic. Think of a situation there is a company that need  more than 5 computers running for doing some data entry stuff or so. Someone can come up with a solution of deploying the number of the physical computers. But this is the 21^st century. So we can use a one physical computer for the all of the needs with running a bare metal   virtualizing operating system. There are several types of Oss. A most popular OS UnRAID by Lime tech (Paid version). According to the VMware industries their own Operating system. VMware ESXI is their competitor to the global market.

VMware own kernel. A Linux kernel ia started at the first and then gradually load the specialized virtualization components otherwise known as VMkernel components. In this situation the Linux kernel is the primary virtual machine. At normal run time, the VMkernel ( The VMkernel is a microkernel with three interfaces : hardware , guest systems and the service console.) is running on the bare computer. As this OS runs on the bare metal it used special device drivers and those are available for the guest operating system. So the guest OS are limited. However the authorities has published a documentation for this product , the supported hardware platforms, supported maximum memory, no. of processors and the guest operating systems are listed in that.
