System Requirements for Virtual Server Agent with Nutanix AHV

The following requirements are for the Virtual Server Agent with Nutanix AHV.

Nutanix AHV Requirements

  • The Commvault Cloud software is supported with Nutanix AHV versions 4.6, 4.7, 5.0, 5.1.x.x, 5.5.x.x, 5.6.x, 5.8.x, 5.9.x, 5.10.x, 5.11, 5.15, 5.16, 5.17.x, 5.18.x, and 5.20.x, 6.0, and 6.5.

  • For application-consistent backups of user VMs, verify that user VMs can access Nutanix controller VMs using the CVM Virtual IP (port 2074).

  • You can install a Commvault Cloud backup gateway on a virtual machine or a physical server in an on-prem datacenter. For more information, see On-Premises Deployment of a Commvault Cloud Backup Gateway.

  • Verify that the Backup Gateway can communicate with Nutanix AHV using Prism port 9440.

  • For Nutanix controller VMs (CVMs), configure a cluster virtual IP.

  • If you are using V3 API, to run backups, your user account must have admin permissions (super user) with all roles defined, or you must configure AD services, and then map the AD user account to the Cluster Admin role and Self Service Portal admin roles via their Self Service Portal.

  • For application-consistent backups of user virtual machines, verify that the following requirements are met:

    • Install Nutanix Guest Tools software on each virtual machine (VM).

    • Verify that the CVM Virtual IP (port 2074) is accessible from user VMs.

    • Update the cluster to Nutanix AHV version 4.6 or later.

    • If virtual machines are added in a user-created protection domain, then the Nutanix Administrator must enable the Use Application Consistent Snapshots option in the Nutanix console while adding these virtual machines. However, if the virtual machines are not added in a user-created protection domain, then the Commvault Cloud software automatically creates a protection domain and enables the application consistent backup feature during the backup operation.


      You cannot create application-consistent snapshots of virtual machines that contain delta, SATA, or IDE disks.

Nutanix Cloud Clusters (NC2) with Microsoft Azure

Commvault Cloud supports data protection and management for Nutanix Cloud Clusters (NC2) on Azure. For more information, see Commvault Data Protection for Nutanix Cloud Clusters on Azure.

Quiescing for Application-Consistent Backups

Windows VMs take application-consistent snapshots using the Volume Shadow Copy Service (VSS) framework.

Linux VMs use pre-freeze and post-thaw scripts instead of VSS. The scripts are located in /sbin/pre_freeze and /sbin/post_thaw folders. The user account that runs the scripts must have root:root access with 700 permissions.


To perform application-consistent backups, each virtual machine must be in a separate consistency group. If a subclient includes a consistency group with multiple VMs, the backup for those VMs fails.

Guest Operating Systems

The virtual machines that you want to back up can have any of the guest operating systems that are supported by the Nutanix AHV platform.


Certain third-party software and service releases (together, "Releases") may not be supported by Commvault. You are solely responsible for ensuring Commvault’s products and services are compatible with any such Releases.
