: Embed vEOS into automated DevOps pipelines to validate infrastructure-as-code scripts (Ansible, Terraform) using simulation tools like GNS3, EVE-NG, or Containerlab.

: Minimum 1 vCPU (2 vCPUs recommended for faster boot times and control plane stability).

vEOS expects hardware checksum offload. Fix: Disable offloads on the VMXNET3 adapter in vSphere: ethtool -K eth0 tx off rx off (inside vEOS bash shell). veos-4.27.0f.vmdk
