Linux Virtualization


I want to review a little about Virtualization in Linux, where I have been discussing a bit about the current Tend Virtualization warm at this time be IT.

Virtualization support for this course, used special software to create a virtualization of an Operating System (OS). In addition to the software would also need to support Hardware Virtualization in full, especially the processor.

Virtualization software for Linux in quite a lot of options, from a paid to that. Generally, the software also have the Windows OS platform.

Who have paid for VMWare that is famous since the first to do a very good virtualization. Flatform available for Windows and Linux OS. While this has also been supporting processor that supports virtualization, both from the Intel and AMD based.

For a free virtualization software, or free, there is VirtualBox and Qemu. Both also have virtualization support on the processor at this time and can be consumed by anyone for free. Featured also is not offered with the paying less. Especially VirtualBox GUI very similar interfacenya with VMWare. Qemu to require installation of kernel mode to activate the special full virtualization on the processor used, while VirtualBox does not require it, because by default already supporting processor that supports virtualization.

To select the processor that has been supporting virtualization, you can mengeceknya in each web. To check on the internet can be here, and AMD can also check the website here. For Intel technology generally known as the Intel VT-x and AMD are usually referred to as AMD-V technology.

This technology allows the processor to the Operating System (OS) that we emulasi or that virtualization can have on the use or access the processor directly, such as using the OS directly without virtualization. So that in the virtualization of the OS will have the speed, compatibility and feature of the processor if you use the same OS that is not in the virtualization software.

In Ubuntu (because I use Ubuntu) can download the Qemu from Synaptic or from the console termoinal:

$ sudo apt-get install qemu qemu-launcher qtemu

For VirtualBox, please download here

For me on Linux to use VirtualBox, because the kernel does not need to activate a special feature of the processor that supports virtualization, and also display its GUI will be very familiar to users VMWare before.


So we do not have to worry using the Linux-based server if you want to use virtualization technology trends that are at this time. While in Linux require additional software again. To use the server for Ubuntu, please use the Ubuntu Server kernel or server, because of course we need RAM memory is big enough that if this will make virtualization.
