Executive Summary This paper provides a deep look at the performance implications of the live storage migration of a VM running a large SQL Server database workload. Performance of the workload when migrating different components of the database (data, index, and log) was measured and compared against the steady state performance (when there was no migration). Experiments discussed in this pape...

Process migration involves moving the running state of a process from one physical system to another, as is commonly done for virtual machines. In this paper, we describe how Content Centric Networking (CCNx) facilitates process migration through an intuitive naming ontology and version checkpointing. 1Computing Science Laboratory, PARC *corresponding author: [email protected]

Resource management in private clouds is a more challenging task than in public clouds. Because there are only finite resources in private cloud compare to public cloud with vast resources. Often, marginal resources are assigned to the application in the private cloud, which causes to the changes of service level of application executions. A resource management system is responsible for fulfill...

Multicore architectures are employed more and more in todays system. A main task of current operating systems is to equalize the load of each CPU’s core, it is accomplished by the migration policy of an operating system. Nevertheless, the migration policy of an operating system is mostly entangled in the kernel. Thus, migration policies of guest kernels running within virtual machines may contr...

System level virtualization provides several advantages: (i) customization is eased since virtual machines may be based on different systems; (ii) virtual machines are isolated from hardware, subsequently applications are isolated via the virtual machines; (iii) basic fault tolerance mechanisms – pro-active fault tolerance through virtual machine migration and virtual machine snapshot/restore; ...

Nowadays, the use of clusters in research centers or industries is undeniable. Since few years, the usage of virtual machines (VM) offers more advanced resource management capabilities, using features such as virtual machine live migration. Because of the latest contributions in the domain, some may argue that single system image (SSI) technologies are now deprecated, without considering some c...
