Introduction to “guestshell_4.1.10.2.8.M.ova” Software
The guestshell_4.1.10.2.8.M.ova is a secure Linux container environment for Cisco Nexus 9000 Series switches running NX-OS 10.2(8)M, designed to enable Python-based automation workflows while maintaining strict resource isolation from the core network operating system. This Open Virtual Appliance (OVA) package provides pre-configured Python 3.8 runtime with Cisco-approved libraries for NETCONF/YANG model operations and telemetry data collection.
As part of Cisco’s Network Services Orchestrator ecosystem, this release introduces enhanced compatibility with Kubernetes-based CI/CD pipelines and Ansible Tower integration. The 4.1.10 version specifically addresses memory management vulnerabilities identified in previous Guest Shell implementations, making it mandatory for environments requiring NIST 800-53 compliance.
