Ubuntu was developed by UK-based Canonical Ltd. It is a company which is owned by South African entrepreneur Mark Shuttleworth. This company generates revenue by the sale of technical support and other services which is related to Ubuntu. The Ubuntu project is publicly committed to the principles of open-source software development. Moreover, people are encouraged to use software for free.
Features
A default installation of Ubuntu contains an ample range of software which includes Firefox, LibreOffice, Transmission,Thunderbird and lots of lightweight games like – chess and Sudoku. There are so many additional software packages too & it includes titles that is no longer in the default installation like GIMP, Evolution, Synaptic, and Pidgin. It is accessible from the built-in Ubuntu Software Center and also in any other APT-based package management tool. Execution of Microsoft Office or any other Microsoft Windows applications can be facilitated through the Wine compatibility package and also by the use of a virtual machine like VirtualBox or VMware Workstation.
LTS in Ubuntu
LTS is an abbreviation in Ubuntu, and it stands for “Long Term Support”. It produces a new Ubuntu Desktop, and the Ubuntu Server offers the new release in every six months. It means you always be able to have the latest and the greatest applications which the open source world offers. Ubuntu is designed in a way with security in mind.
Different Derivatives
It has nine flavours and dozens of localized and specialized derivatives today. There are also special editions for servers in it, clouds techniques and mobile devices are also there. All editions share same infrastructure and software which makes Ubuntu a unique single platform & really easy to use. It scales from consumer electronics to the desktop and up into the cloud for enterprise computing i.e. everywhere.
Operating System for Ubuntu Server
The Ubuntu OS and the innovative Ubuntu for Android convergence solution make it an exciting time for Ubuntu on mobile devices. In the cloud, Ubuntu is the reference operating system for the Open stack project, it is a hugely popular guest OS of various vendors whether it is online or offline. Because of shared infrastructure, developers can work on the desktop and smoothly deliver code to cloud servers running the stripped down Ubuntu Server Edition. After so many years Ubuntu is still and always will be free to use, share and develop. It is hoped by its makers that it will bring a touch of light to users computing and user will join them in helping to build the next version.

Virtual machine
Virtual Machine (VM) is an emulation of a particular computer system. Its operation is based on the computer architecture and functions of a real or hypothetical computer, and their implementations may involve specialized hardware, software or a combination of both.
Classification of virtual machines can be based on the degree to which they implement functionality of targeted real machines. System virtual machines (also known as full virtualization VMs) provide a complete substitute for the targeted real machine and a level of functionality required for the execution of a complete operating system. On the other hand, process virtual machines are designed to execute a single computer program by providing an abstracted and platform-independent program execution environment.
System Virtual Machine
A system virtual machine is a virtual machine which provides a complete system platform that supports the execution of complete operating system (OS). It usually emulate an existing architecture, and is built with the purpose of providing a platform to run programs where real hardware is unavailable for use such as – executing on otherwise obsolete platforms or having multiple instances of virtual machines. It leads to more well-organized use of computing resources, both in terms of cost effectiveness and energy consumption.
Conclusion
That’s all for Ubuntu server virtual machine host, it is virtual due to the reason, it works inside & virtually in desktop, laptop, Smartphone or tablet. It is a guest operating system & do its work within the VM, whether it host someone else or self.
