The file is a virtual disk image used to run Arista's vEOS (virtual Extensible Operating System) in a virtualized environment. vEOS is a virtual machine version of Arista’s EOS , designed for network simulation, testing, and lab development.

For a modern, containerized approach, containerlab supports vEOS nodes. You would typically reference the image in a topology file. Detailed documentation is available on the official containerlab website, which notes that nodes come pre-provisioned with SSH, SNMP, NETCONF, and gNMI services enabled.

When you deploy veos-4.27.0f.vmdk , you are launching a Linux-based OS (EOS is built on Fedora) with a unique twist: a forwarding plane that operates in one of two modes:

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.
