| 20080320242 | PHYSICAL MEMORY CAPPING FOR USE IN VIRTUALIZATION - A method of implementing virtualization involves an improved approach to resource management. A virtualizing subsystem is capable of creating separate environments that logically isolate applications from each other. Some of the separate environments share physical resources including physical memory. When a separate environment is configured, properties for the separate environment are defined. Configuring a separate environment may include specifying a physical memory usage cap for the separate environment. A global resource capping background service enforces physical memory caps on any separate environments that have specified physical memory caps. | 12-25-2008 |
| 20080320474 | DYNAMIC, TEMPORARY RESOURCE POOLS FOR USE IN VIRTUALIZATION - A method of implementing virtualization involves dynamic, temporary resource pools. A virtualizing subsystem is capable of partitioning a plurality of physical resources to create resource pools. The virtualizing subsystem is further capable of creating separate environments that logically isolate applications from each other, and assigning a created separate environment to a created resource pool. A separate environment is configured by defining properties of the separate environment. Configuring the separate environment includes specifying at least one resource pool attribute. When the separate environment is started, a temporary resource pool is created from available physical resources and the separate environment is assigned to the temporary resource pool. The temporary resource pool is created in accordance with the at least one resource pool attribute specified when the separate environment was configured. The temporary resource pool may be destroyed when the separate environment is shutdown. | 12-25-2008 |
| 20090007126 | SWAP CAP RESOURCE CONTROL FOR USE IN VIRTUALIZATION - A method of implementing virtualization involves an improved approach to virtual memory management. An operating system includes a kernel, a resource control framework, a virtual memory subsystem, and a virtualization subsystem. The virtualization subsystem is capable of creating separate environments that logically isolate applications from each other. The virtual memory subsystem utilizes swap space to manage a backing store for anonymous memory. The separate environments share physical resources including swap space. When a separate environment is configured, properties are defined. Configuring a separate environment may include specifying a swap cap that specifies a maximum amount of swap space usable by the separate environment. The resource control framework includes a swap cap resource control. The swap cap resource control is enforced by the kernel such that during operation of the separate environment, the kernel enforces the swap cap specified when the separate environment was configured. | 01-01-2009 |
