High-performance live migration
Accelerate live migration performance with compression or RDMA-capable network adapters
For <10GBit network connectivity, live migration compression delivers superior performance – 2x acceleration for most workloads
For >10GBit networks, Remote direct memory access (RDMA) offload delivers the highest performance with low CPU utilization and transfer speeds of up to 56Gb/s
Windows Server 2012 R2 supports RoCE, iWARP and Infiniband RDMA solutions

1 User Initiates an export of a running VM
2Hyper-V performs a live, point-in-time export of the VM, which remains running, creating the new files in the target location
3 Admin imports new, powered-off VM on the target host, finalizes configuration and starts VM
4 With Virtual Machine Manager, Admin can select host as part of the clone wizard
