VM migration

Virtualization is all about flexibility. Migration is one of the features in virtualization that showcase its flexibility. What is migration then? In simple terms, it enables you to move your virtual machine from one physical machine to another physical machine with a very minimal downtime or no downtime.

There are two types of migration: offline and online migration.

Offline migration

As the name suggests, during offline migration, the state of the VM will be either shut down or suspended. The VM will be then resumed or started at the destination host.

Live or online migration

In this type of migration, the VM is migrated to the destination host while it's running on the source host. The process is invisible to the users who are using the virtual machines. They will never know that the virtual machine they are using has been transferred to another host while they are working on it. Live migration is one of the main features that made virtualization so popular.
