How does Live Migration work in Windows Server 2008 R2? fawad 25-November-2008 09:24:12 AMComments In the first version of Hyper-V, you had the ability to perform Quick Migration, which was the process where a virtual machine (VM) running on a node in a cluster could be moved to another node in the cluster with a minimal amount of downtime. The exact amount of downtime was basically the time it took to write the content of the VM's memory to the LUN, moving the LUN to the new node, provisioning the VM on the new node and reading the memory from the LUN. Typically all of this would be done in about 30 seconds for a machine with a couple of gigabytes of memory. For many organizations, 30 seconds of planned downtime is acceptable.
