File attribute information is shared between processes running on a virtual machine and processes accessing a virtual hard disk from a host level. When a host level process accesses files on a virtual hard disk, that process updates the relevant file attribute information, and stores the updated file attribute information on the virtual hard disk. When a virtual machine level process subsequently accesses files on the virtual hard disk, that process reads the updated file attribute information, and omits unnecessary operations. When a virtual machine level process accesses files on the virtual hard disk and updates the corresponding file attribute information, that process communicates the updated file attribute information to the host. When a host level process subsequently accesses files on the virtual hard disk, the host level process reads the updated file attribute information. |
