Methods, systems, and products are disclosed for saving unsaved user process data in one or more logical partitions (‘LPARs’) of a computing system, the computing system having installed upon it a hypervisor for administering the LPARs, each LPAR supporting an operating system, each operating system supporting one or more user processes, that include: detecting, by the hypervisor, a predefined event that the hypervisor interprets as an indication that unsaved data of user processes for at least one LPAR should be saved; transmitting, by the hypervisor in response to detecting the predefined event, a save instruction to the operating system supported by the LPAR; and instructing, by the operating system in response to receiving the save instruction, each user process supported by the operating system to save any unsaved data.
