A provisioning server automatically configures a virtual machine according to user specifications and then deploys the VM on a physical host. The support member includes a first end and a second end. According to other aspects, the present invention allows for simultaneous optimization of both source and mask, thereby significantly speeding the overall convergence. Right hand and left hand upper ramp sections of the nozzle ramp may be connected to right hand and left hand upper nozzle wall sections respectively of the upper nozzle wall which are pivotally connected to right and left handed triangular side walls of the aft end.
