    摘要: Memory is managed by controlling the expansion of memory contents, especially in those computing environments in which the memory contents are compressed. Control is provided by imposing some restrictions to memory references outside a specified subset of the memory contents, and by controlling the transfer of items into the subset. In one example, the transfer of items into the subset is based on a function of parameters, including an estimate of the amount of free space in the memory.

    摘要: A computer implemented method, a computer program product, and data processing system clone virtual machines in a virtual desktop environment. A request to clone a new virtual machine is intercepted, wherein the request was initially sent to a virtual management server. Responsive to intercepting the request, the new virtual machine is cloned from a snapshot of a master virtual machine. A delta file is created for the new virtual machine, wherein the delta file includes a base disk reference and a copied delta file. The new virtual machine is configured to read a base disk image from a snapshot of the master virtual machine. The new virtual machine is configured to write data to the copied delta file in the delta file.

    摘要: A system and method for extracting data from a protected region of memory loads at least a first part of extraction code into physical memory and, thereafter, activates a memory mapping facility that maps a real memory onto the physical memory and prevents programs from accessing a protected memory region of the physical memory. At least a second part of the extraction code is then loaded into the virtual memory utilizing the memory mapping facility. The extraction code is then executed to deactivate the memory mapping facility and to copy data from the protected memory region to a second physical memory region, such that reactivating the memory mapping facility will cause a real memory region to be mapped onto the second physical memory region.
