Virtual machines can be remotely configured on distributed host devices by communicating management instructions over remote access tunnels. The ferrule according to the present invention can be fused to optical fibers, capillaries and the like while reducing deformation of the fused component and the ferrule. The optimal template size for template matching is the one that provides the best matching performance which is calculated from the minimum entropy of the parameter estimate. The VM is then placed on the selected host computer system using the hardware multithreading parameter. The scaled video stream and the scaled graphics stream are then merged to produce a video graphics output stream.
