What the netlab Vagrant/libvirt Sunset Means for Network Labs

netlab is sunsetting the Vagrant/libvirt provider that helped teams build virtual network environments from text configuration files. The provider began as an extension of netlab's early Vagrant and VirtualBox support, using the vagrant-libvirt plugin to add KVM/libvirt environments.

Why the Provider Sunset Matters

A declarative lab may look portable, but its operation can still depend on a specific virtualization backend. Removing the provider can therefore affect topology startup, device access, integration scripts, CI jobs, and the assumptions embedded in team documentation.

The immediate task is to find every workflow that explicitly or implicitly expects Vagrant/libvirt. Teams can then distinguish reusable topology intent from provider-specific configuration that must be replaced.

From Infrastructure as Code to Backend Dependency

Vagrant became popular for describing virtual environments in text, helping popularize an infrastructure-as-code approach. According to the source, it was not an ideal match for netlab's use case, illustrating how tools can become difficult to sustain when used far beyond their original purpose.

The lesson is not to abandon declarative labs. It is to keep lab definitions, automation logic, and virtualization dependencies separated enough that one backend can be changed without redesigning the entire workflow.

Practical Migration Options

Teams affected by the sunset can use several paths to preserve reproducibility:

• Move lab definitions to a provider supported by the current netlab release and documentation.
• Remove provider-specific assumptions from scripts before testing them against another backend.
• Keep topology intent, addressing, device roles, and automation inputs in version-controlled text files.
• Build a small representative topology first, then validate startup, connectivity, device access, and teardown behavior.
• Temporarily preserve a pinned legacy environment while migration testing proceeds, rather than changing production automation and the lab backend at the same time.
• Record prerequisites and repeatable setup steps so another operator or CI runner can rebuild the environment.

Protecting Network Automation During the Transition

A replacement lab is only useful if it exercises the same operational paths. Validation should include the automation that loads configurations, checks device state, gathers results, and resets the environment between tests.

Comparing the old and new workflows on a limited topology can expose backend-specific timing, connectivity, or access assumptions before they disrupt broader testing. The goal is not merely to make devices boot, but to retain a repeatable environment for network changes and automation development.

Where ConnectMyAssets Fits

ConnectMyAssets does not replace a network lab provider. It supports the operational stage after tested configurations and automation are applied to managed network infrastructure.

• Automation & ZTP supports mass deployment and zero-touch provisioning across supported network vendors.
• Backup & History records configuration versions with SHA256 verification and provides one-click rollback.
• Dynamic CMDB automatically discovers assets and builds LLDP-based topology context.
• Compliance Engine evaluates managed configurations against frameworks including NIS2, ISO 27001, PCI-DSS, CISA, and NIST.
• Credential Vault centralizes the credentials used for controlled infrastructure access.

Because ConnectMyAssets runs as a hardened on-prem OVA, network inventory, configurations, credentials, and operational history remain on-prem. This gives teams a controlled management layer for moving validated changes from reproducible labs into multi-vendor environments.
