While QCOW2 is versatile, its features add a processing overhead compared to raw disk images. Reads and writes require metadata lookups and management, which can slightly slow I/O operations. However, for networking labs where CPU and RAM are often the primary bottlenecks, this storage overhead is usually negligible.

Filename may vary slightly (e.g., iosxrvk9demo-6.13.0.qcow2 ), but the guide applies to all 6.x demo versions. iosxrvk9demo613qcow2 top

For running automated background topologies, native hypervisors are highly efficient.
