Introduction to guestshell_4.0.10.4.1.F.ova Software

The ​​guestshell_4.0.10.4.1.F.ova​​ is a preconfigured virtual machine image for Cisco Nexus 9000 Series switches, designed to deploy a secure Linux-based container environment within NX-OS. This software enables network engineers to run custom automation scripts, diagnostic tools, and third-party applications directly on Nexus switches without compromising the stability of the primary operating system.

Compatible with NX-OS 10.3(x) and later releases, this Guestshell package (version 4.0.10.4.1.F) aligns with Cisco’s software-defined infrastructure strategy. While official release notes don’t specify an exact publication date, version patterns indicate Q4 2024 compatibility updates for Nexus 9300-EX/FX3 and 9500 platforms.


Key Features and Improvements

This Guestshell iteration introduces critical enhancements for network automation:

  1. ​Security Hardening​

    • SELinux policy updates compliant with NIST 800-193 guidelines
    • Isolated container resource limits to prevent CPU/memory exhaustion attacks
  2. ​Platform Support​

    • Extended Python 3.11 runtime with cryptography module v42.0+
    • Ansible Nexus 2.8 collection preinstalled for infrastructure-as-code workflows
  3. ​Performance Optimizations​

    • 40% reduction in container startup time compared to v3.x releases
    • Persistent storage allocation increased to 2GB by default
  4. ​Management Integration​

    • RESTCONF API endpoints for container lifecycle management
    • Enhanced logging integration with Nexus telemetry streams
