Does virtual machine live migration refer to moving VMs between physical servers while they are still running?

Live migration of virtual machines (VMs) refers to the process of moving a running VM from one physical server to another without interrupting the operation of the VM. This capability is essential in cloud computing environments where workloads can be dynamically adjusted based on resource availability, load balancing, or maintenance needs. The primary advantage of live migration is that it minimizes downtime, allowing for seamless service continuity for end users.

In this scenario, stating that live migration does not occur highlights a misunderstanding of the term. Live migration specifically emphasizes that VMs are indeed moved while actively running, rather than being powered off, which is the central concept that defines it.

Other options, while touching on the subject, either constrain the definition unnecessarily by referring to specific conditions, such as network constraints or power states, or misinterpret the fundamental principle of live migration as it applies broadly to operational VMs in various configurations.
