VM Management
Core VM management operations can be done directly from Prism without using any hypervisor management interface. Once your Nutanix nodes are added to your vCenter instance and your vCenter Server is registered with your Nutanix cluster (Settings > vCenter Registration), you can perform the following operations directly through Prism:
- Creating, cloning, updating, and deleting VMs
- Creating and deleting NICs
- Attaching and deleting disks
- VM Power operations (on/off, reset, suspend, resume, guest shutdown, guest restart)
- Launch VM console
- Manage VM guest tools (VMware or Nutanix Guest Tools)
