@shwstppr might sourceHyperHost be null as well ?

@weizhouapache Method gets sourceHyperHost either from caller or the host which is processing the command,

@shwstppr if the origin is a merge commit than this should be fixed on the older branch and merged forward.

VirtualMachineDiskInfo diskInfo = diskInfoBuilder.getDiskInfoByBackingFileBaseName(newPath, dsMo.getName());
