What does VMotion allow you to do?

VMotion is a key feature of VMware vSphere that allows for the live migration of a powered-on virtual machine from one physical host to another with no downtime. It enables administrators to move workloads across hosts for reasons such as load balancing, hardware maintenance, energy conservation, or facilitating high availability. The critical aspect of VMotion is that it achieves this migration seamlessly, ensuring that users do not experience any interruption and that there is no impact on the application’s availability.

In contrast, the other options do not accurately describe what VMotion is designed to do. Performing backups of virtual machines is associated with disaster recovery and data protection solutions, not VMotion. Restarting a virtual machine involves stopping and starting the VM, which is contrary to the zero-downtime goal of VMotion. Lastly, provisioning new virtual machines is related to the initial setup and allocation of resources for new instances and is not a function of VMotion, but rather part of the deployment process together with tools like vSphere Web Client or vCenter Server.
