Abstract
Official abstract text for this publication.
A technique for assigning physical resources of a data processing system to a virtual machine (VM) includes reading, by a hypervisor executing on the data processing system, a fold factor attribute for the VM. The fold factor attribute defines an anticipated usage of physical resources of the data processing system by the VM. The technique also includes mapping based on a value of the fold factor attribute, by the hypervisor, allocated virtual processors of the VM to the physical resources to maximize processor core access to local memory for ones of the allocated virtual processors that are anticipated to be utilized.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of assigning physical resources of a data processing system to a virtual machine, comprising: in response to a virtual machine (VM) being instantiated, reading, by a hypervisor executing on a data processing system, a fold factor attribute for the VM, wherein the fold factor attribute defines a user specified anticipated usage of physical resources of the data processing system by the VM; and mapping based on a value of the fold factor attribute, by the hypervisor, allocated virtual processors of the VM to the physical resources such that processor core access to local memory that is not located within a processor is maximized for ones of the allocated virtual processors that are anticipated to be utilized, wherein the fold factor attribute includes a processor fold factor attribute that defines a percentage of the allocated virtual processors of the VM that are anticipated to be utilized and a memory fold factor attribute that defines a percentage of required memory of the VM that is anticipated to be utilized. 2. The method of claim 1 , wherein the physical resources include multiple processor cores. 3. The method of claim 2 , wherein the physical resources include respective local memory associated with each of the multiple processor cores. 4. The method of claim 1 , wherein the physical resources include multiple processor cores, memory, and input/output (I/O).
