Nutanix Requirements

DMC supports scanning of Windows and Linux servers hosted on Nutanix with the following requirements.

Supported Operating Systems

Operating System Support Details
Windows Server 2008 R2 and above Collects metrics for Windows servers
Ubuntu Collects metrics for Linux servers
Red Hat Collects metrics for Linux servers
CentOS Collects metrics for Linux servers
SUSE Collects metrics for Linux servers

Network Requirements

DMC requires network access to target Nutanix guest VMs within the scope of discovery.

Source Destination Ports Purpose
Jump Box Windows VMs 5985 (HTTP), 5986 (HTTPS) Windows Remote Management (WinRM)
Jump Box Linux VMs 22 (SSH) Linux management and data collection

Windows VM Prerequisites

PowerShell Remoting must be enabled on Windows VMs to allow DMC to run PowerShell commands over WinRM connections.

To enable PowerShell remoting:

  1. Open PowerShell as Administrator on each Windows VM
  2. Run the following command: 
    Enable-PSRemoting -force

This enables the WinRM service and configures the necessary firewall rules for remote PowerShell connections.

Credential Requirements

To ensure DMC can perform discovery the following permissions are required.

Windows VM Access

Account Minimum Required Permissions Reason
Domain Admin or Local Admin Interactive Login Rights Required to collect system settings, software inventory, active processes, and network dependencies to assist with environment assessment.

Linux VM Access

Account Minimum Required Permissions Reason
Root or Sudo-enabled user System access for package queries and process monitoring Required to collect system settings, software inventory, active processes, and network dependencies to assist with environment assessment.
ℹ️
Usernames can be entered in either user/domain or user@domain.com format for Windows VMs; both styles are supported.

Least Privilege Guest OS Account Setup

If you prefer to use least-privilege accounts instead of admin accounts, you can set up dedicated user accounts with specific permissions.

Windows VM Accounts

For Windows VMs, you can create a least-privileged Windows user account:

Required Group Memberships:

Group Purpose Alternative
Remote Management Users Enables WinRM connections WinRMRemoteWMIUsers_
Performance Monitor Users Allows performance data collection Required
Performance Log Users Enables performance logging access Required

Required permissions: The account needs these permissions so DMC can create a CIM connection with the server and collect configuration and performance data from the required WMI classes.

⚠️
UAC Filtering Note: Sometimes, even after adding the account to the right groups, it may not return the needed data because of UAC filtering. To fix this, give the user account the right permissions on the CIMV2 namespace and its sub-namespaces on the target server.
ℹ️

Additional Requirements:

  • For Windows Server 2008 and 2008 R2, ensure that WMF 3.0 is installed on the servers.

Linux VM Accounts

You need a user account that has sudo permissions to execute specific commands with NOPASSWD on the Linux VMs you want to discover.

This account helps collect configuration and performance data, perform software inventory (find installed applications), and enable agentless dependency analysis using SSH.

Required sudo access (NOPASSWD):

Command Purpose Full Path
netstat or ss Network connection analysis /usr/bin/netstat, /usr/bin/ss
ps Process information /usr/bin/ps
ls File system listing /usr/bin/ls

Sudoers file entry example:

username ALL=(ALL) NOPASSWD: /usr/bin/netstat, /usr/bin/ss, /usr/bin/ps, /usr/bin/ls
⚠️
Important: Ensure that you enable NOPASSWD for the account so it can run the required commands without asking for a password each time it uses sudo. Also modify the sudoers file to disable terminal (requiretty) for the user account.

SSH Key Requirements

For Linux VMs, DMC supports SSH private keys created using the ssh-keygen command with the following algorithms:

Algorithm Support Details
RSA Full support for RSA key pairs
DSA Full support for DSA key pairs
ECDSA Full support for ECDSA key pairs
ed25519 Full support for ed25519 key pairs
⚠️

Important Notes:

  • SSH keys with passphrases are not supported. Use keys without a passphrase.
  • SSH private key files created by PuTTY are not supported.
  • Only SSH private key files in OpenSSH format are supported.
