Which of the following VMware ESXi VM migration solutions are capable of migrating VMs without first powering off or suspending them? (Choose two.)
- cold migration
- Storage vMotion
- vSphere vMotion
Of the available choices, only VMware vSphere vMotion and Storage vMotion are capable of migrating VMware ESXi virtual machines (VMs) without first powering off or suspending them. VMware’s ESXi server is a bare-metal server virtualization technology, which means that ESXi is installed directly on the hardware it is virtualizing instead of running on top of another operating system (OS). This layer of hardware abstraction enables tools like vMotion to migrate ESXi VMs from one host to another without powering off the VM, enabling the VM’s users to continue working without interruption.
VMware’s vSphere vMotion can be used to migrate a VM’s virtual environment from one host to another. However, vSphere vMotion does not migrate datastores. Storage vMotion, on the other hand, allows migration of both the VM and its datastore. The datastore is the repository of VM-related files, such as logs and virtual disks. When migrating a VM by using Storage vMotion, both the virtualized environment and the datastore can be moved to a new host without powering down or suspending the VM.
Cold migration cannot migrate a VM without powering down or suspending the VM. Cold migration is the process of powering down a VM and moving the VM or the VM and its datastore to a new location. While a cold migration is in progress, no users can perform tasks inside the VM.
Neither copying nor cloning can migrate a VM. Both copying and cloning create new instances of a given VM. Therefore, neither action is a form of migrating a VM to another host. Typically, a VM must be powered off or suspended in order to successfully copy or clone it.
