Currently, there are some unit tests that are failing on Windows due to various reasons: - Different "File not found" error messages on Windows. - Files need to be closed on Windows before removing them. - The default RootHnsEndpointName (root-hnsendpoint-name) flag value is 'cbr0' - On Windows, Unix Domain sockets are not checked in the same way in golang, which is why hostutils_windows.go checks for it differently. GetFileType will return an error in this case. We need to check for it, and see if it's actually a Unix Domain Socket.
