Veos-4.27.0f.vmdk Here
| Format | Use Case | Pros | Cons |
|--------|----------|------|------|
| VMDK (this article) | VMware vSphere / Workstation | Native performance, snapshot support, easy integration with NSX | Commercial hypervisor required |
| QCOW2 | KVM / OpenStack | Open source, better live migration | Conversion needed |
| Raw /vEOS-lab | Container Lab (cEOS) | Minimal resource use (~500 MB RAM) | Reduced feature set (no MLAG) |
| OVA | Quick deployment | Preconfigured hardware | Harder to customize |
Cause: vEOS’s polling mechanism (DPDK-like) conflicts with ESXi CPU scheduler.
Mitigation: Set CPU affinity for vEOS VM to core sibling pairs. Alternatively, reduce CPU polling interval: bash → sudo sysctl -w net.core.busy_read=0. veos-4.27.0f.vmdk
By default, the VMDK begins a 30-second boot countdown. You can skip this by adding to your .vmx file: | Format | Use Case | Pros |
bios.bootDelay = "1000"
