Managing virtual machines requires different roles to perform some tasks. For example, only a fabric administrator can change the reservation of a virtual machine, but a machine owner can create a snapshot of a virtual machine.
Reconfigure a Machine vSphere, vCloud Director, and SCVMM platforms support reconfiguration of existing machines to accommodate changes in workload demand.
Change the Reservation of a Virtual Machine A fabric administrator can change the reservation of a virtual machine. This ability is useful when a virtual machine moves to a new storage path that is not available in its current reservation.
Create a Snapshot of Your Machine Depending on how your administrators have configured your environment, you might be able to create a snapshot of your virtual machine. A snapshot is an image of a virtual machine at a specific time. It is a space-efficient copy of the original VM image. Snapshots are an easy way to recover a system from damage, data loss, or security threats. After you create a snapshot of your virtual machine, you can apply it and reset your system back to the point where the snapshot was taken.
