Abstract: The Cloud Service providers have to manage the resources that are available more efficiently to provide services according to Service Level Agreement. Virtual machines use the hardware effectively which reduces the need of physical hardware. Due to some circumstances like system crashes, increase in load on server, the virtual machines need to be migrated to other host machines. In live migration the virtual machines are moved to other host machines while they are running. In this paper, we propose a Log-Table based Migration algorithm for maximizing the availability of Cloud Services to the Cloud Users while migrating the Virtual Machines. During live migration, this algorithm maximizes the availability of high priority cloud services to the users under the constraints of load on network bandwidth and time. Experimental results shows that this algorithm performs well at heavy workload conditions by providing services to the cloud users according to Service Level Agreement.
