Repack - Cat9kv-prd-17.12.01prd9.qcow2

Virtualizing enterprise networks requires robust, stable, and highly scalable virtual routing platforms. The filename represents a production-ready disk image for Cisco's virtual routing infrastructure. Specifically, this file contains the Cisco Catalyst 8000V (Edge Software) or the virtualized Catalyst 9000 switching/routing code running IOS-XE Cupertino 17.12.1.

Historically, simulating true Cisco Catalyst Layer 2 and Layer 3 switching features in a virtual lab was difficult due to the tight integration of Cisco's proprietary hardware Application-Specific Integrated Circuits (ASICs). Legacy images like VIOS-L2 or IOL (IOS on Linux) offered a basic substitute but lacked the capacity to run modern enterprise feature sets.

After 90 days, the switch enters a "licensing grace period". Features continue to work for another 60 days but will syslog warnings. For perpetual lab use, you will need a Cisco DNA Virtual Subscription (low-cost academic/DEVNET options exist).

The image can be deployed on various platforms, but the process differs significantly.
