PCIe Passthrough
Role in the Homelab
Section titled “Role in the Homelab”The HP t740 uses multiple NICs to bridge Proxmox workloads — especially EVE-NG — to physical ports on the Catalyst 3560-CX. This enables virtual routers and switches to communicate with real hardware in the hybrid lab.
Current Approach
Section titled “Current Approach”EVE-NG runs as a nested VM with:
- CPU mode:
host-passthrough— exposes physical hardware acceleration to the guest. - Network bridges: VirtIO interfaces bridged to physical NICs connected to the 3560-CX.
This is documented in detail in EVE-NG Deployment.
PCIe Passthrough (Planned)
Section titled “PCIe Passthrough (Planned)”Dedicated PCIe NIC passthrough to the EVE-NG VM (bypassing Linux bridge overhead) will be documented here once configured. Target use cases:
- Direct attachment of a physical NIC to EVE-NG cloud interfaces.
- Lower latency for high-throughput lab scenarios.
