What are essential steps of live VM migration?
Live migration takes place between two Hyper-V hosts. Essentially, the VM memory is copied between Hyper-V hosts. After the memory is copied, the VM on the new host can access its virtual hard disk (VHD) files and continue to run. Both hosts access shared storage where the VM’s VHD files are stored.
How many steps are involved in live migration of VM?
As shown in Figure 3.20, live migration of a VM consists of the following six steps: Steps 0 and 1: Start migration. This step makes preparations for the migration, including determining the migrating VM and the destination host.
What is the sequence of live migration of a VM?
Live migration refers to the process of moving a running virtual machine or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination.
How do I live migrate a VM between Hyper-V hosts?

How can I live and migrate?
Quick Migration and Live Migration require the source and destination hosts to be members of the same failover cluster. Live Migration within a cluster requires at least one cluster network to be enabled for Live Migration. Right-click on the Networks node in Failover Cluster Manager and click Live Migration Settings.
How long does a VM migration take?
Perform Live Migrations
Transfer the virtual machine’s active memory and precise execution state over a high-speed network, allowing the virtual machine to switch from running on the source vSphere host to the destination vSphere host. This entire process takes less than two seconds on a gigabit Ethernet network.
Why is it necessary to migrate a virtual machine?
Migration of virtual machine is gaining more importance today to improve utilization of resources, load balancing of processing nodes, isolation of applications, tolerating the faults in virtual machines, to increase the portability of nodes and to rise the efficiency of the physical server.
Which is last stage of live migration?
In the final stage of a live migration, the migrated virtual machine is running on the destination server. At this point, a message is sent to the network switch.
