SELECTING A HOST FOR A VIRTUAL MACHINE USING A HARDWARE MULTITHREADING PARAMETER

摘要

A cloud manager monitors available resources on host computer systems, including a number of hardware threads supported by CPUs on the host computer systems. The cloud manager receives a request to provision a virtual machine (VM) that includes a hardware multithreading parameter that specifies the amount of hardware multithreading required on the host computer system. The cloud manager then selects a host computer system for the VM taking the hardware multithreading parameter into consideration.

主权项

1. An apparatus comprising:
at least one processor; a memory coupled to the at least one processor; a cloud manager residing in the memory and executed by the at least one processor, the cloud manager comprising:
a host selection mechanism that receives a virtual machine (VM) request that includes a number of virtual CPUs and a hardware multithreading parameter that specifies whether hardware multithreading is required, and when hardware multithreading is required, specifies a minimum number of hardware threads per core, wherein the host selection mechanism selects one of the plurality of host computer systems that satisfies the hardware multithreading parameter and that includes a number of CPUs with a number of hardware threads per core that satisfies the number of virtual CPUs in the VM request.
