The nbdkit.go module has good coverage, but lacks integration tests for the most critical functions: RunNbdKitURI() and RunNbdKitSocks(). These manage NBDKit server lifecycle—the core mechanism for streaming disk data from VMware to OpenStack.

Can be used the pattern of tests/integration/test_flavor_info.yml using Go mock servers to simulate NBD/SOCKS endpoints without requiring actual nbdkit binaries.

What needs to be tested:

• RunNbdKitURI(): HTTP NBD server startup, connection, teardown
• RunNbdKitSocks(): SOCKS proxy setup and routing
• Error handling (port conflicts, process failures)
• Concurrent connections and cleanup
