Introduction to nxosv-final.7.0.3.I7.9.ova
This Open Virtual Appliance (OVA) delivers Cisco NX-OS 7.0(3)I7(9) for Nexus 7000v virtual switches, designed for data center network simulations and DevOps pipeline testing. As part of the “I7” Extended Maintenance Release (EMR), this build provides long-term stability for hybrid cloud environments while maintaining feature parity with physical Nexus 7700 series hardware.
Compatible with VMware ESXi 6.7+ and KVM hypervisors, this version resolves 15 CVEs disclosed in previous releases. Cisco officially published this security-enhanced package in Q2 2025 to address critical vulnerabilities in VXLAN and BGP-LU implementations.
