Survey of security Problems raised by virtualization in cloud computingenvironment

Cloud computing has emerged as a main form ofmodern computing due to its many advantages. Cloud computinginfrastructures enable companies to cut costs by outsourcingcomputations on-demand. Cloud computing is a service modelfor IT provisioning, often based on virtualization and distributedcomputing technologies. Cloud computing already leveragesvirtualization for load balancing via dynamic provisioning andmigration of virtual machines (VM or guest in the following)among physical nodes. This paper tries to identify virtualizationsecurity issue in cloud computing environment and presents anoverview of virtual machine's vulnerabilities and shows that thewidely used virtual machine managers cannot be consideredfully secure.
