Abstract
The present disclosure relates to flexible processor association for virtual machine instances. One example method includes initializing a virtual machine instance on a particular computing device, the particular computing device including a plurality of physical processors, determining a maximum number of the physical processors available to be associated with the virtual machine instance; initializing a number of virtual processors for use by the virtual machine instance, the same as the maximum number of the physical processors; associating the virtual machine instance with a number of the physical processors less than the maximum number of the physical processors; during execution of the virtual machine instance: identifying a change in a demand metric associated with the virtual machine instance; and adjusting the number of the physical processors associated with the virtual machine instance based on the identified change in the demand metric while maintaining the number of virtual processors.
