Nutanix Guest Tool NGT Installations in Windows and Linux VM

Nutanix Guest Tools (NGT) is a set of software features already downloaded and installed within a VM and a Nutanix CVM. A Nutanix guest agent (NGA) publishes information about the VM to the Nutanix cluster, such as guest OS type, VM mobility status, and VSS services. The NGA is installed in both Windows and Linux guests.

Nutanix Volume Shadow Copy Service (VSS)

The Nutanix VSS hardware provider enables integration with native Nutanix data protection. The provider allows for application-consistent, VSS-based snapshots when using Nutanix protection domains. Supported with Windows guests.

Self-Service Restore

The Self-Service Restore (SSR) feature enables Nutanix administrators or VM owners to mount snapshots directly to the VM from which they were taken. This capability allows end users to select the specific files they wish to use from a given snapshot.

The Self-Service Restore GUI and CLI are installed in Windows guests. The Nutanix Guest Tools CLI (ngtcli) is used to execute the SSR CLI.
Access the SSR GUI by opening a browser, navigating and logging on with machine administrator rights.

Nutanix VirtIO Drivers

NGT installs the Nutanix VirtIO drivers and provides the registry configuration necessary to support the migration or conversion of VMs bidirectionally between AHV and ESXi.

These drivers are used when performing Nutanix VM Mobility or Nutanix cluster conversion.The required drivers are installed in Windows guests.

NGT requires network connectivity between the Nutanix cluster and the user VMs. NGT also requires an empty IDE CD-ROM slot in the guest for attaching the ISO image.

For NGT communication with the Nutanix cluster, ensure that the Nutanix cluster is configured with a virtual IP address (VIP). Also ensure that port 2074 is open between the required VMs and the CVMs.

NGT can be enabled from either Prism (VM page, table view) or the Nutanix CLI (nCLI) on a VM-by-VM basis. When first enabled, NGT mounts an ISO to the specified VM.

An administrator can then run the NGT installer from inside the VM. After installation, the installer package ejects the CD-ROM and enables NGT for the VM.

VSS snapshot functionality is enabled by default, while self-service restore, previously called file-level restore, is disabled by default. To view or modify services, or control ISO mount state, use Prism by selecting the target VM and choosing Manage Guest Tools. nCLI can also be used, specifically the ngt command. The following example shows how to query the NGT state for a specific VM.

Nutanix Guest Tools Recommendation

Only install NGT within guests as required for the following use cases:

  • For VMs that require self-service restore.
  • For VMs that require VSS.
  • Prior to performing a cluster conversion.
  • When utilizing Nutanix VM Mobility.

If none of these conditions apply, use the Nutanix VirtIO driver standalone installation package and not NGT.
