Placement of virtual CPUs 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 whether hardware multithreading is allowed on the host computer system. The cloud manager then selects a host computer system for the VM taking the hardware multithreading parameter into consideration. The VM is then placed on the selected host computer system using the hardware multithreading parameter.

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 a plurality of host computer systems that satisfies the hardware multithreading parameter and that includes a number of CPUs with a number of hardware threads that satisfies the number of virtual CPUs in the VM request; anda virtual CPU (vCPU) placement mechanism that uses the hardware multithreading parameter to place a plurality of virtual CPUs (vCPUs) on the selected host computer system.
