: Often converted to QCOW2 format for native QEMU integration.

Before configuring complex top-of-rack or spine-leaf fabrics using veos-4.27.0f.vmdk , note the differences between virtualized testbeds and real hardware devices: Supported Testing Paradigms veos-4.27.0f.vmdk

Some images are marked as "combined," meaning they include the Aboot bootloader. If you use a non-combined image, you may need a separate Aboot ISO to boot the VM.

Unlike physical Arista switches that run on custom hardware ASICs, vEOS runs a modified control plane optimized for standard x86 servers. It uses the exact same CLI, API (eOS API or eAPI), and Linux-based core as physical Arista switches. This makes it an ideal tool for testing configurations before pushing them to production.
