1. Introduction to asav9-17-1-13.qcow2 Software
The asav9-17-1-13.qcow2 file represents Cisco’s Adaptive Security Virtual Appliance (ASAv) 9.17(1) release, designed for enterprise-grade virtual firewall deployments on KVM hypervisors. This QCOW2-format image provides full ASA firewall functionality in virtualized infrastructures, enabling security policy enforcement across hybrid cloud architectures and software-defined networks.
Released on December 1, 2021, this build introduces enhanced interoperability with Cisco Firepower Management Center 7.4+ while maintaining backward compatibility with ASA 9.16+ configurations. The software supports deployment in private clouds using KVM/libvirt stacks and integrates with Cisco’s Application Centric Infrastructure (ACI) for SDN environments.
