Managing virtual machines

Discover virtual machine management in Prism Central

Last updated 10th May 2022


Find out how to manage virtual machines in a Nutanix cluster, and how to create and migrate a virtual machine.

OVHcloud provides services for which you are responsible, with regard to their configuration and management. It is therefore your responsibility to ensure that they work properly.

This guide is designed to assist you as much as possible with common tasks. Nevertheless, we recommend contacting a specialist provider if you experience any difficulties or doubts when it comes to managing, using or setting up a service on a server.

Some software requires a licence such as Microsoft products, so make sure that all installed systems and software have these licences.

  • access to the OVHcloud Control Panel
  • You must be connected to Prism Central on the cluster

Overview of Virtual Machine Management in Prism Central

The Nutanix system uses the same interfaces to manage storage and virtualisation, it can be installed with multiple hypervisors (Hyper-V, VMware ESXi, AHV). AHV comes with Nutanix without the need to purchase additional licences for the hypervisor.

The OVHcloud solution is delivered with the AHV hypervisor.

AHV enables:

  • Using virtual machines on Windows and Linux.
  • Migrating virtual machines from one node to another in a cluster.
  • Micro-segmentation and network security between virtual machines using Flow software.

The Move tool makes it easy to migrate existing virtual machines in other environments (ESXi, Hyper-V & AWS) to Nutanix and its AHV hypervisor.

For more information on AHV, see the Go further section of this guide.


The following instructions show the creation of a virtual machine in Windows Server 2022 and the migration of a virtual machine.

Migrating a virtual machine

Migrating a virtual machine involves moving a hot VM from one node to another in a cluster.

If you have several clusters and the appropriate licences, you can also migrate a VM from one cluster to another.

This guide only shows you how to migrate a VM within the same cluster.

In Prism Central VM Management, click WS2022N.

Migrate - VM01

Check which node the VM is currently running on. It is displayed next to Host.

Migrate - VM02

Click the More button, then Migrate.

Migrate - VM03

Choose a destination node.

Migrate - VM04

The name of the new node will appear in front of Host if the migration is complete.
