摘要： In response to a request received from a guest alignment module, host alignment module determines a target starting location in a virtual hard disk to which the beginning of a guest partition of a virtual machine is written. Host alignment module translates a guest partition's virtual hard disk address into a physical hard disk address and determines whether the physical hard disk address is track aligned with disk tracks of the physical hard disk. If the physical hard disk address is not track aligned, host alignment module determines a new track aligned physical hard disk address as the target starting location. If the physical hard disk address is track aligned, the same physical hard disk address is used as the target starting location. The target starting location is returned to the guest alignment module as a new virtual hard disk address.

摘要翻译： 响应于从访客对准模块接收到的请求，主机对准模块确定写入虚拟机的客户分区开始的虚拟硬盘中的目标开始位置。 主机对准模块将访客分区的虚拟硬盘地址转换为物理硬盘地址，并确定物理硬盘地址是否与物理硬盘的磁盘轨道对齐。 如果物理硬盘地址未跟踪对齐，则主机对齐模块确定新的跟踪对齐的物理硬盘地址作为目标起始位置。 如果物理硬盘地址跟踪对齐，则使用相同的物理硬盘地址作为目标起始位置。 目标起始位置作为新的虚拟硬盘地址返回给访客对齐模块。
