If based on common IOSv release:

Use WinSCP or FileZilla to upload the .vmdk file into that folder.

The virtual image file is an authorized, virtualized Cisco IOS router image designed explicitly for network simulation, labs, and educational environments. Originally distributed through Cisco VIRL (Virtual Internet Routing Lab) and later integrated into Cisco Modeling Labs (CML), this specific image provides an official, stable alternative to legacy hardware emulation. It allows engineers to run modern Cisco features on commodity server and desktop hardware. vios-adventerprisek9-m.vmdk.spa.156-2.t

: Practice Multi-Protocol Label Switching (MPLS), Layer 3 VPNs, and DMVPN (Dynamic Multipoint VPN).

Because it packages the engine, this image supports complex networking architectures. This makes it a primary tool for engineers studying for professional-level certifications like the Cisco Certified Network Professional (CCNP) and Cisco Certified Internetwork Expert (CCIE) . If based on common IOSv release: Use WinSCP

: Indicates that the image runs in the router's Extended Memory space.

Always keep a "clean" base image so you can wipe and restart labs quickly.

It boots faster than most hardware routers but may take 1–2 minutes to reach a console prompt depending on your disk speed.

After conversion, rename the resulting file to virtioa.qcow2 for proper platform detection in some environments.
