Abstract
Methods and apparatus allocate and adjust memory of a hardware platform hosting a plurality of guest virtual machines. One of the virtual machines is configured as a management domain that determines whether other virtual machines comply with a performance computing policy. If not, an initial amount of memory for the other virtual machines is adjusted higher or lower. In this manner, the guest machines are each outfitted with sufficient memory to accomplish their respective workloads, and such is adjusted over time as workloads vary per machine. This distributes throughput concerns throughout an entire platform to sufficiently guarantee a quality of service for each machine of the platform, regardless of its individual tasks. Other features contemplate specific computing policies regarding page fault rates and computer program products for assisting in the foregoing, to name a few.
