Virtuozzo Linux 

VzLinux is a free-to-use open-source Linux-based operating system used in commercial products. This is based on the RHEL (Red Hat Enterprise Linux) releases.  

Qualys supports the two versions of the Vituozzo Linux: 

  1. Virtuozzo Linux 8: A 1:1 clone of Redhat Enterprise Linux (RHEL) 8. 
  2. Virtuozzo Linux 9: A 1:1 clone of Redhat Enterprise Linux (RHEL) 9. 

Signature Detection 

Virtuozzo Hybrid Server 6 

The server reached the End of Life (EOL) cycle in Nov 2021. So, Qualys will release EOL QIDs for the Virtuozzo Hybrid Server 6 in the upcoming week. 

Virtuozzo Hybrid Server 7 

Qualys adds support for the upstream patches made available by RedHat.  

Qualys adds QIDs based on the vendor advisories for upstream patches, but after 2020, there is no update on the vendor advisory

Virtuozzo Linux 8 and 9 

There are no publicly available vendor advisories for the Virtuozzo Linux 8 and 9 as of now. Qualys will add QIDs based on the advisories once they are made available by the vendor.  

Here is an example of the scan results for the Information Gathering QID 45017. The scan results show Virtuozzo Linux 7, 8, and 9. Please refer to the screenshots below:
