In this paper, we have proposed a technique using Raspberry Pi board as a small PC with Docker to implement the concept of virtualization. Docker which is used for running distributed applications in an open platform. This implementation shows how efficient it will be to implement server virtualization technique on simple computers like raspberry pi. The outcome will be a virtualized Raspberry Pi which will run various applications on the hypervisor. This method involves booting Arch Linux into the Raspberry Pi, and then installing a hypervisor into it. Virtual machines will be installed and keep running in the background. If the power consumed with virtualization is less than the power consumed when these processes are running in different hardware without any virtualization then it is concluded that virtualization is saving power and also reducing the hardware involved. Power monitoring software is used to measure the power consumed by the raspberry pi. © Springer International Publishing Switzerland 2016.
