“…Moreover, the above analyses based on queueing theory are all under the assumption that the edge node serves perfectly. However, the failure of a server or a VM can reduce the processing capability of the edge node directly and increase latency [ 12 , 40 , 41 ]. To model the failure and repair of VMs, VMs can be treated as unreliable and repairable queue servers based on the multi-server queueing models with unreliable and repairable servers [ 20 , 21 , 22 , 23 , 26 ].…”

For the edge computing network, whether the end-to-end delay satisfies the delay constraint of the task is critical, especially for delay-sensitive tasks. Virtual machine (VM) migration improves the robustness of the network, whereas it also causes service downtime and increases the end-to-end delay. To study the influence of failure, migration, and recovery of VMs, we define three states for the VMs in an edge server and build a continuous-time Markov chain (CTMC). Then, we develop a matrix-geometric method and a first passage time method to obtain the VMs timely reliability (VTR) and the end-to-end timely reliability (ETR). The numerical results are verified by simulation based on OMNeT++. Results show that VTR is a monotonic function of the migration rate and the number of VMs. However, in some cases, the increase in task VMs (TVMs) may conversely decrease VTR, since more TVMs also brings about more failures in a given time. Moreover, we find that there is a trade-off between TVMs and backup VMs (BVMs) when the total number of VMs is limited. Our findings may shed light on understanding the impact of VM migration on end-to-end delay and designing a more reliable edge computing network for delay-sensitive applications.

Computing allows users to migrate their intentions to distributed environment which will utilize more number of possessions to complete execution rapidly. Virtualization means numerous virtual machines on single machine. During development of migration, VM move one physical appliance to another. In offline migration, procedure is stopped till the virtual machine can endure on target machine, while in live migration process can execute without intermittent. Live migration is a migration during which the VM seems to be receptive all the time from clients' outlook. In Data centre, live migration of virtual machine performs significant role. Live migration has been expensively used in load balancing, energy decrease and active resizing to increase availability and hardware conservation. This cause removal of huge number of redundant memory pages resulting into increase in the total migration time and downtime.

“…QEMU emulator is used to run guest OS instances along with real and backend drivers. ITRI is one of few mobile hypervisors that supports guest migration [34]. The performance evaluation of native and VM based execution show negligible overhead in compute intensive tasks while five times overhead in worst case for I/O intensive tasks.…”

Virtualization is generally adopted in server and desktop environments to provide for fault tolerance, resource management, and energy efficiency. Virtualization enables parallel execution of multiple operating systems (OSs) while sharing the hardware resources. Virtualization was previously not deemed as feasible technology for mobile and embedded devices due to their limited processing and memory resource. However, the enterprises are advocating Bring Your Own Device (BYOD) applications that enable co-existence of heterogeneous OSs on a single mobile device. Moreover, embedded device require virtualization for logical isolation of secure and general purpose OSs on single device. In this paper we investigate the processor architectures in the mobile and embedded space while examining their formal virtualizabilty. We also compare the virtualization solutions enabling coexistence of multiple OSs in Multicore Processor System-on-Chip (MPSoC) mobile and embedded systems. We advocate that virtualization is necessary to manage resource in MPSoC designs and to enable BYOD, security, and logical isolation use cases.
