When the EVE-NG community first started adopting vIOS images, the standard procedure was to obtain the qcow2 images by mounting the CML reference platform ISO and copying the files to the appropriate addons directory. A CML account holder can download images from their dedicated download location on Cisco's website, provided they maintain a valid CML license.
3. Integrating vios-adventerprisek9-m.spa.159-3.m6.qcow2 into Simulations
For users who cannot immediately obtain a CML subscription, community-maintained repositories provide another avenue. One particularly relevant resource is the GitHub repository maintained by hegdepavankumar, which hosts a collection of Cisco and other vendor images specifically for GNS3 and EVE-NG. This repository explicitly states that the images are "Free Images for EVE-NG and GNS3" and are intended "only for personal practices and preparations for self-growth in the Network and Security field".
If you still need a legitimate source, use the exact filename in Cisco’s download portal (requires login). Example: vios-adventerprisek9-mspa.159-3.m6.qcow2 viosadventerprisek9mspa1593m6qcow2 download better
If you are building a virtual networking lab using GNS3, EVE-NG, or Cisco Modeling Labs (CML), you have likely come across the filename viosadventerprisek9mspa1593m6qcow2 . This specific file refers to the for CSR 1000v, specifically the Advanced Enterprise Services feature set with the SPA (Shared Port Adapter) hardware emulation layer.
Always compare the SHA512 or MD5 checksum of your downloaded file against the one provided on the official Cisco download page to ensure no data was lost or altered.
: If running on generic QEMU/GNS3, calculate and apply an Idle-PC value to prevent the virtual idle loop from consuming 100% of your physical CPU core. When the EVE-NG community first started adopting vIOS
Re-download and verify the MD5/SHA512 hash. Conclusion
Once you have securely acquired the image, it is typically used in GNS3 or EVE-NG. Setting up in EVE-NG
: Supports advanced enterprise features like MPLS, VRF, OSPFv3, EIGRP, BGP, DMVPN, and legacy IPv6 transitions. There are two primary ways to legally obtain
Cisco packages all necessary, tested virtual images ( qcow2 formats for routers, switches, ASA, and Nexus) directly into the CML distribution media.
There are two primary ways to legally obtain this specific qcow2 image:
