I would like to provide feedback on the documentation related to Virtual Machine Threat Analysis.

The current documentation explains Threat Analysis behavior mainly from a Linux perspective

, but it does not clearly mention OS compatibility requirements between the Threat Scan Server and the guest OS of the VM being scanned.

Based on validation in multiple environments, the following behavior is observed:

  • Linux Threat Scan Server → supports Linux VM threat analysis

  • Linux Threat Scan Server → does not support Windows VM threat analysis

  • Windows VM threat analysis works correctly only when a Windows Threat Scan Server is used

This indicates a design requirement, not a troubleshooting issue:

  • Windows VMs must be scanned using a Windows Threat Scan Server

  • Linux Threat Scan Server is intended for Linux VMs only

This requirement is currently not clearly documented, which may lead to incorrect design assumptions during deployment.

If you have a question or comment, please create a topic

Hi ​@Yassmin Omer, we added a note to cover the point you mentioned, Here’s the doc link - Threat Analysis for Virtual Machine Backups.

HI ​@csawant 

Thank you very much for your support and for updating the documentation based on this discussion.

I really appreciate the effort and responsiveness of the Commvault team. This clarification will definitely help the community and avoid confusion around Threat Scan access node requirements.

​@csawant  I have noticed that the Note added in 11.42 is not the same as in 11.40

https://documentation.commvault.com/11.40/software/threat_analysis_for_virtual_machine_backups.html

If we really need a Threat Scan OS matching the Guest OS then it should be correctly explained in version 11.40 documentation as current note talks about “optimal performance”

Thanks in advance!
