Determining Placement Fitness For Partitions Under A Hypervisor

摘要

A technique for determining placement fitness for partitions under a hypervisor in a host computing system having non-uniform memory access (NUMA) nodes. In an embodiment, a partition resource specification is received from a partition score requester. The partition resource specification identifies a set of computing resources needed for a virtual machine partition to be created by a hypervisor in the host computing system. Resource availability within the NUMA nodes of the host computing system is assessed to determine possible partition placement options. A partition fitness score of a most suitable one of the partition placement options is calculated. The partition fitness score is reported to the partition score requester.

1: A method for determining NUMA node placement fitness for virtual machine partitions that can be provisioned on said NUMA nodes with each virtual machine partition occupying one or more of said NUMA nodes, said virtual machine partitions being managed under a hypervisor in a host computing system having non-uniform memory access (NUMA) nodes, and each comprising a set of computing resources that include processor, memory and I/O resources, comprising:
receiving from a partition score requester a partition resource specification identifying a set of computing resources, including processor, memory and I/O resources, needed for a virtual machine partition to be created by a hypervisor in said host computing system, said partition score requester being a resource manager agent that provisions virtual resources in response to resource requests from customer devices; assessing resource availability within the NUMA nodes of said host computing system to determine possible partition placement options representing one or more NUMA nodes where said virtual machine partition with said needed computing resources could be provisioned; calculating a partition fitness score of a most suitable one or more NUMA nodes representing one of said partition placement options; said partition fitness score reflecting an ability of said hypervisor to provision said computing resources within a single one of said NUMA nodes; and reporting said partition fitness score to said partition score requester.
