Determining Placement Fitness For Partitions Under A Hypervisor

Abstract

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 placement fitness for partitions under a hypervisor in a host computing system having non-uniform memory access (NUMA) nodes, comprising:
 receiving from a partition score requester a partition resource specification identifying a set of computing resources needed for a virtual machine partition to be created by a hypervisor in said host computing system;   assessing resource availability within the NUMA nodes of said host computing system to determine possible partition placement options;   calculating a partition fitness score of a most suitable one of said partition placement options; and   reporting said partition fitness score to said partition score requester.   
     
     
         2 . The method of  claim 1 , wherein said partition fitness score reflects an ability of said hypervisor to provision said computing resources within a single one of said NUMA nodes. 
     
     
         3 . The method of  claim 1 , wherein said partition fitness score comprises predetermined categories. 
     
     
         4 . The method of  claim 1 , wherein said partition fitness score comprises a numeric gradation value that may be weighted to favor different resource characteristics. 
     
     
         5 . The method of  claim 1 , further including receiving a reservation request based on said partition fitness score and reserving said computing resources for use in fulfilling a partition provisioning request. 
     
     
         6 . The method of  claim 1 , wherein said partition fitness score reflects an ability of said hypervisor to provision said computing resources within a single resource pool in said host computing system. 
     
     
         7 . The method of  claim 1 , wherein said partition fitness score reflects an ability of said hypervisor to provision computing resources for a set of partitions.
