Embodiments of the invention disclose a storage control method for a distributed virtual machine, and the virtual machine. The storage control method is applied to the virtual machine in a distributed system comprising N physical disks; the physical disks are located on one side of a host machine; a small physical disk in each physical disk has a serial number; the physical disks have large physical disk identifiers; the small physical disks have small physical disk identifiers; and the large physical disk identifiers are combined with the serial numbers of the small physical disks to obtain the small physical disk identifiers. According to the scheme, the subsequent physical disks can be searched for conveniently and the congestion is reduced; and in addition, the data congestion possibility can be reduced, the data storage parallelism can be improved, and the data storage security can be improved. 本发明实施例公开了种分布式虚拟机的存储控制方法、及虚拟机；应用于包含N个物理磁盘的分布式系统中的虚拟机，所述物理磁盘位于宿主机侧；每个物理磁盘内的小物理磁盘具有序号；所述物理磁盘各自具有大物理磁盘标识，小物理磁盘具有小物理
