SyncSnap: Synchronized Live Memory Snapshots of Virtual Machine Networks
2014 IEEE Intl Conf on High Performance Computing and Communications, 2014 IEEE 6th Intl Symp on Cyberspace Safety and Security, 2014 IEEE 11th Intl Conf on Embedded Software and Syst (HPCC,CSS,ICESS), 2014With the prevalence of virtualization technology, virtual machine networks (VMN) have been widely used in host network applications. To provide fault tolerance and non-stop features to network applications and preserve the network consistency among virtual machines (VM), the distributed snapshot technique of virtual machine networks regains the ...

A Framework of Page Synchronization for Adaptable Virtual Machine Live Migration
2019 IEEE Intl Conf on Dependable, Autonomic and Secure Computing, Intl Conf on Pervasive Intelligence and Computing, Intl Conf on Cloud and Big Data Computing, Intl Conf on Cyber Science and Technology Congress (DASC/PiCom/CBDCom/CyberSciTech), 2019Cloud computing employs live migration to relocate virtual machines such that service interruption can be minimized. Total migration time and service downtime are important meters for measuring the efficiency of live migration. In this paper, a framework of iterative page synchronization is proposed for adaptable live migration.

Implementation of a Virtual Synchronous Machine to Improve the Dynamic Response of Inverters
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019This paper proposes a control technique that allows inverters to work as if they were synchronous machines, assuming the characteristics and properties that these machines have. The development of each control block that composes the Virtual Synchronous Machine (VSM) is presented.

A lock-aware virtual machine scheduling scheme for synchronization performance
The Journal of Supercomputing, 2015In virtualized environments, multiprocessor virtual machines encounter synchronization problems such as lock holder preemption (LHP) and lock waiter preemption (LWP). When the issue happens, a virtual CPU (VCPU) waiting for such locks spins for an extraordinarily long time and wastes CPU cycles seriously, resulting in a significant degradation of ...
