Infrastructure as a Service (IaaS) on the cloud requires more machines to provide services. Therefore the virtualization technology that can use a physical machine as multiple independent virtual machines has become a hot topic. Virtualization technology can increase the utilization rate of physical machines, but it also increases the losses caused by machine failures. Fault Tolerance (FT) becomes a very effective solution for this problem. A fault-tolerant VM system can use several architectures and technology for implementation. Continuous checkpointing is one popular way for achieving the state of the fault-tolerant system by uninterrupted synchronization of the virtual machine states between the main machine and the backup machine, and is also the architecture adopted in this study. This study is based on “QEMU-3.0.0”. We present several implementation techniques and demonstrate its efficiency and overhead in the paper.
