Method for distributing hypervisor memory requirements across logical partitions

A system for reallocating memory to a hypervisor in a virtualized computing system, the system comprising:

• a hypervisor with a configuration manager, memory, and a plurality of logical partitions;
• wherein the configuration manager assigns priorities to the plurality of logical partitions, determines a memory requirement for the hypervisor, determines minimum levels of memory required for each of the plurality of logical partitions, and determines the amount of available memory in the virtualized computing system not committed to the plurality of logical partitions;
• and
• in the event that the amount of available memory is less than the determined memory requirement of the hypervisor, the configuration manager removes portions of memory from one or more of the plurality of logical partitions based on the assigned priorities until the determined memory requirement for the hypervisor is obtained.

An article comprising one or more computer-readable storage media containing instructions that when executed enable a computer to implement a method of reallocating memory to a hypervisor in a virtualized computing system;

• wherein the method further comprises:
• assigning priorities to a plurality of logical partitions configured within the virtualized computing system;
• determining a memory requirement for the hypervisor, the hypervisor configured to manage the plurality of logical partitions;
• determining minimum levels of memory required for each of the plurality of logical partitions;
• determining the amount of available memory in the virtualized computing system;
• and
• in the event that the amount of available memory is less than the determined memory requirement of the hypervisor, removing portions of memory from one or more of the plurality of logical partitions based on the assigned priorities until the determined memory requirement for the hypervisor is obtained.
