Hi,
Along with the new version of Cisco CML 2.10.0, new image versions have been released, including new versions of Cisco IOL.
The new IOL images are no longer .qcow2 files. I'm wondering if it will be possible to run them in eve-ng?

Yes, older images were .bin files, but new images are .qcow2, please see here: https://www.eve-ng.net/index.php/docume ... -on-linux/

New refplat_iso contains IOL image in new format, a tar.gz archive. It is no longer a file with the .bin or .qcow2 extension inside

Since version 17.18.2, they stopped shipping a binary and switched to distributing it as a Docker image.
Because of that, the old method won’t boot the node anymore.
Guess I’ll just have to wait for a proper Docker template to drop…
