In this thesis, pre-copy live VM migration using Distributed Shared Memory (DSM) computing model is proposed. The setup is built using two identical computation nodes to construct all the proposed environment services architecture namely the virtualization infrastructure (Xenserver6.2 hypervisor), the shared storage server (the network file system), and the DSM and HPC cluster. Your controller must include an NVMe over InfiniBand host port; otherwise, the NVMe over InfiniBand settings are not available in System Manager. You must know the IP address of the host connection. The NVMe over InfiniBand settings and functions appear only if your storage array's controller includes an NVMe over InfiniBand port.
