FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -VM migration is the most important feature of virtualization. With this feature an OS state is transferred from one computing node to another physical node. There are two different techniques of migration, first is pre-copy migration and the second is post-copy migration technique.

Detailed explanation-2: -VMware vSphere live migration allows you to move an entire running virtual machine from one physical server to another, with no downtime. The virtual machine retains its network identity and connections, ensuring a seamless migration process.

Detailed explanation-3: -Hyper-V live migration moves running virtual machines from one physical server to another with no impact on virtual machine availability to users. By pre-copying the memory of the migrating virtual machine to the destination server, live migration minimizes the transfer time of the virtual machine.

Detailed explanation-4: -Depending on the virtual machine resource type, you can perform three types of migration. Moving a virtual machine, but not its storage, to another compute resource, such as a host, cluster, resource pool, or vApp. You can move the virtual machine to another compute resource by using cold or hot migration.
