For a Linux server, you might name it linux-rocky-9.6 . For a Cisco CSR1000v, a name like csr1000vng-16x is typical. For Arista vEOS, a structure like veos-4.34.1F is used.
Let’s walk through downloading and preparing an image—a common pain point. eveng qemu images download better
Better approach: Don’t download a bloated Windows 10 image. Instead:
Create a new lab, add the node, and start it. A better download will boot in under 60 seconds and not spike your CPU beyond 30%. : Leo learned that using qemu-img convert -c
QEMU images are large; a single Cisco CSR1000v can exceed 1.5 GB, and a collection of twenty images can easily surpass 30 GB. Slow, interrupted downloads are a major pain point. Here is how to do better.
mkdir -p /opt/unetlab/addons/qemu/<your-image-name> cd /opt/unetlab/addons/qemu/<your-image-name> For Arista vEOS, a structure like veos-4
: All images must reside in /opt/unetlab/addons/qemu/ .
Skip the installation wizard phase and boot directly into a configured command-line interface (CLI) or web interface.
