Embodiment Construction

[0028] In the following description, for purposes of explanation, specific details are set forth in order to provide a thorough understanding of embodiments of the invention. It will be apparent, however, that various embodiments may be practiced without these specific details. The drawings and descriptions are not intended to be limiting.

[0029] Certain embodiments of the present invention enable a virtual machine (VM) to dynamically modify or change resources assigned or allocated to the VM while the VM is operating without having to stop, restart, or restart the VM. One or more resources may be dynamically added to (assigned or assigned to) or removed (deallocated) from a VM while the VM is operating, without having to restart, restart, or stop the VM whose resource allocation is changing. Dynamically changing the resource allocation of a VM means that a certain amount of resources can be allocated to or deallocated from an already executing or started VM without having ...

Abstract

Certain embodiments enable resources assigned or allocated to an operating virtual machine (VM) to be modified while the VM is operating and without having to stop, restart, or reboot the VM. The modification may correspond to increasing or decreasing the amount of a resource being assigned to the VM. In this manner, resources assigned to a VM at the time of creation of the VM are not static and can instead be dynamically changed while the VM is operating without having to stop, reboot, or restart the VM. In some embodiments, the changes to the resources allocated to one or more VMs provided for a user (e.g., a customer) may be made according to or in response to a Service Level Agreement (SLA) entered into by the user, in response to an event such as a failover or switchover event, and the like.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 61 / 666,227, filed June 29, 2012, entitled "DYNAMIC RESOURCE ALLOCATION FOR VIRTUAL MACHINES" and filed March 12, 2013, entitled "DYNAMIC RESOURCE ALLOCATION FOR VIRTUAL MACHINES" Benefit of filed U.S. nonprovisional application No. 13 / 796,136, which claims priority to U.S. provisional application No. 61 / 666,227. The entire contents of the 61 / 666,227 and 13 / 796,136 applications are hereby incorporated by reference for all purposes. Background technique [0003] The present disclosure relates generally to virtualization, and more particularly, to techniques for dynamically changing the resources allocated to a virtual machine (VM) while it is operating. [0004] The increase in systems and devices with multiple processors or processors with multiple cores associated with advances in virtualization technology has led to a rapid increase in the use of virtual machines...
