I hit “Start All Nodes” in EVE-NG. Fifteen Arista vEOS nodes began decompressing at the same time. Half the nodes didn’t fully boot and required that I stop them, wipe them, and restart them.
That’s the datacenter fabric for this lab: 15 vEOS switches across three sites, eBGP underlay, EVPN overlay, all running inside EVE-NG on the same Proxmox host as the CML SP core. Getting them configured was the easy part (Nautobot templates handle that). Getting them to actually boot was the first real problem.
Each box gets a startup-config in EVE-NG so it comes up reachable. Production config is a Golden Config push from Nautobot.
If you want to reproduce this, you’ll need two VMs on a Proxmox host (or any KVM hypervisor). CML needs 12 vCPU, 80 GB RAM, and 80 GB disk for the 13 Cisco cat8000v nodes. EVE-NG needs 8 vCPU, 64 GB RAM, and 80 GB disk for the 15 Arista vEOS nodes. That’s roughly 144 GB total RAM for the network layer alone. You’ll need the EVE-NG VM running with the Blog-SandBox topology loaded.
