The vendored Vagrant VirtualBox provider has a regression in private-network configuration. Repair the existing provider source, preserving its public APIs and version-specific VBoxManage parsing.
A private network's name may be either the stable host-only interface name or
the display name reported by VBoxManage. Make the common network action resolve
the display form to the canonical interface name before adapter setup. Ensure
the legacy driver parsers and the VirtualBox 7 host-only-network adapter expose
the same normalized display_name field while retaining their native address,
mask, IPv6, and status behavior. The generic action must use the portable
host-only interface inventory; the host-only-network inventory is only a
Darwin/VirtualBox-7 implementation detail. Keep the shared driver facade's
delegation surface synchronized with the versioned inventory APIs.
Canonical interface names must continue to resolve unchanged. An unknown name must remain unknown rather than selecting the first available interface.
Work directly in the existing files under vendor/vagrant. Do not add a
replacement evaluator or hard-code the fixture's interface name. The vendored
upstream tests are available for code-reading context, but do not install gems
or attempt the full upstream suite. Finish by running:
python3 /app/contract_runner.py > /app/contract_result.json
The command must succeed offline and leave the declared artifact at that exact
path. The JSON artifact must declare
output_schema_version = "vagrant.virtualbox.network-contract.v1" and report the
cross-version inventories, the three name-resolution outcomes, portable API
call counts, Meta delegation status, and the sorted result-key list produced by
the supplied runner.
