The file includes the virtualized forwarding engine. In a physical Catalyst 9300, this is an ASIC (Application Specific Integrated Circuit). In the cat9kv , this is a software module that creates the dp-core to process packets in the CPU. This is why the host CPU resources matter for throughput on this image.

: Supports modern automation tools like NETCONF, RESTCONF, and gNMI. cat9kv-prd-17.12.01prd9.qcow2

Unlike its predecessors, this image supports newer features like Programmability (NETCONF/RESTCONF) and more advanced Layer 2/3 capabilities. The file includes the virtualized forwarding engine

The 17.12 release train is significant because it represents a maturation point for the "IOS-XE Dublin" code base (the modern, Linux-OS-based architecture). This is why the host CPU resources matter

: Enables virtualized testing of Software-Defined Access (SDA) environments.

While powerful, users on forums like Reddit frequently note that it is technically distributed as a beta VM image and can crash if you push high traffic throughput.
