VIRTUALIZATION AND TELEPORTATION OF FILES AMONG VIRTUAL BOXES

Abstract

Cloud Computing popularity has grown on recent years. Providing infrastructure and software as a service proved to be very efficient for big and small organizations to rent software and infrastructure providing by others. Organizations mostly rent infrastructure in form of virtual machines with some sort of resources. Those virtual machines run on some physical machines which are hidden from the user. Science in most cases usage of virtual machines varies, cloud provider can manage resource acquisition from virtual machines so they can offer more than their infrastructure supports. This is done by live migration. By using live migration resource load can be balanced therefore the service offered by cloud provider is better and also cloud providers can offer more than they actually have. Even if it is a good solution, teleportation has a small drawback as it requires a small amount for the virtual machine to be down. Recent researches are focused on how to minimize this downtime. On our thesis we will run a simulation of live migration through virtual box. We created firstly two virtual machines on two hp laptops and performed live migration from one pc to another. We repeated experiment twice, on the first one we executed commands from both computers while on the second one we executed commands from one computer. We used telnet for remote control. We also wrote a script in python which can connect with target and destination host and perform automatically the teleporting of virtual machine just by running script on a third machine. As telnet server we used Pragma telnet. The experiments were successful and we managed to get a minimum downtime of the virtual machine. Also the data was successfully transferred from one machine to another without loss.
