Introduction to “asav-esxi.mf”
The asav-esxi.mf is a critical deployment manifest file accompanying Cisco ASAv (Adaptive Security Virtual Appliance) images for VMware ESXi environments. This metadata file ensures proper installation of ASAv virtual machines by defining resource allocation, network mappings, and hardware compatibility rules. As part of Cisco’s virtual firewall solutions, ASAv 9.14.2+ requires this manifest to enable advanced features like SR-IOV network acceleration and vSphere Distributed Switch integration.
Compatible with VMware ESXi 6.7 U3 to 8.0U2, the package supports both traditional x86_64 and ARM-based hypervisors. Cisco released this version in Q4 2023 to address growing demand for hypervisor-optimized security appliances in hybrid cloud architectures.
Key Features and Improvements
1. SR-IOV Configuration Validation
- Automatically detects compatible Intel XXV710/Mellanox NICs during deployment
- Prevents VM boot failures by verifying PCIe passthrough prerequisites
2. Resource Optimization
- Enforces minimum 4 vCPU/8GB RAM allocation for 10Gbps throughput profiles
- Implements NUMA node affinity rules to reduce latency by 18%
3. Security Compliance
- Integrates FIPS 140-2 validated boot process for government deployments
- Blocks deployment on end-of-life ESXi versions (6.5 and earlier)
Compatibility and Requirements
| Component | Minimum Requirement | Recommended |
|---|---|---|
| VMware ESXi | 6.7 U3 | 8.0 U2 |
| vCenter Server | 7.0 | 8.0 U1 |
| Host CPU | Intel Haswell/AMD Zen1 | Intel Ice Lake/AMD Zen3 |
| Network Adapter | 10Gbe NIC | 25Gbe SR-IOV capable |
Known Limitations:
- Incompatible with VMware Workstation Pro
- Requires full administrator privileges for OVA import
