Introduction to asav9-19-1-9.qcow2

The asav9-19-1-9.qcow2 represents Cisco’s KVM-optimized virtual machine image for Adaptive Security Virtual Appliance (ASAv) version 9.19(1)9, designed for enterprise-grade firewall implementations in private cloud environments. This QCOW2 format package provides consistent security policy enforcement across virtualized data centers while maintaining compatibility with legacy on-premises infrastructure.

As part of Cisco’s 9.19 Extended Maintenance Release (EMR) track, this build delivers extended lifecycle support through Q3 2025 for organizations requiring stable network segmentation policies. The image specifically targets financial and healthcare sectors operating hybrid infrastructures with strict compliance requirements.

Virtualization Platform Minimum Resources Supported ASAv Models
KVM (QEMU 5.2+) 8 vCPU, 32GB RAM, 250GB storage ASAv10, ASAv30, ASAv50
VMware ESXi 7.0 U3+ 6 vCPU, 24GB RAM, 200GB storage ASAv100, ASAv300
Microsoft Hyper-V 2022 10 vCPU, 48GB RAM, 300GB storage ASAv500, ASAv1000

​​Critical Compatibility Notes:​​

  • Requires VMware Tools 12.2.0+ for ESXi deployments
  • Incompatible with Firepower Threat Defense 7.2+ policy configurations
  • Mandatory AES-NI instruction set enabled on host processors

Verified Software Access

The asav9-19-1-9.qcow2 image requires active Smart License with Threat Defense entitlement through Cisco’s Enterprise Agreement program. While this version remains available for legacy infrastructure support, production environments should consider migrating to ASAv 9.22.x releases for current threat intelligence integrations.
