Virtualisation

Virtual Operating Sytems

Today I will be talking about how to use virtual box (free software), to create a virtual environment which you can install operating systems on.

Virtual box simply makes an exact copy of your pc, and allows you to operate it in exactly the same way as you would, without the risk of breaking your machine. A virtual environment allows the user to play with various operating systems along with any other settings without any fear of crashing the system, a broken virtual environment can simpy be erased and a new one installed.

Install oracle virtual box...

To install various operating systems the disc image of the OS will first be needed. Then simply click new and follow the instructions to create the virtual system. To install the OS onto the virtual system follow these instructions...

     1.  Settings - storage
     2.  host drive D - click the disc icon
     3.  choose a virtual cd/dvd - choose the OS disk image

Remember to choose a dynamic hard drive, this means that the virtual hard drive will grow as and when it is needed, otherwise it will crash when memory runs out!

 

 

Dont ask why I chose windows 8, I have no idea.

Benefits of Virtualisation

1. Reduce carbon footprint - Migrating physical servers over to virtual machines and consolidating them onto far fewer physical servers means lowering monthly power and cooling costs in the data center.
2. Improve disaster recovery -  by consolidating servers down to fewer physical machines in production, an organization can more easily create an affordable replication site.
3. Help things move to the 'Cloud'.
