Optimizing virtual machine deployment time by temporarily allocating more processing resources during the initial deployment time of the virtual machine

摘要

A method, system and computer program product for optimizing virtual machine deployment time. A cloud controller receives a request from a user to configure a virtual machine with a designated CPU capacity. If the designated CPU capacity is less than or equal to a threshold, then the cloud controller determines if there are additional cloud resources available to be allocated to deploy the virtual machine. If so, then the cloud controller allocates additional CPU capacity to the designated CPU capacity to be used to provision the virtual machine thereby enabling a multithreaded startup to initialize the operating system and middleware tiers so as to reduce the deployment time of the virtual machine. The additional resources would only be available during the initial deployment time of the virtual machine and removed before the user is granted access to the system when it comes online.

1. A method for optimizing virtual machine deployment time, the method comprising:
receiving a request to configure a virtual machine with a designated CPU capacity comprising R CPU cores, wherein said R is a positive real number; determining if said designated CPU capacity is less than or equal to a threshold, wherein said threshold comprises a single CPU core; in response to said designated CPU capacity being less than or equal to said threshold:
provisioning said virtual machine on a hypervisor with a CPU configuration comprising said designated CPU capacity plus an additional CPU capacity;activating said virtual machine utilizing said designated CPU capacity plus said additional CPU capacity; andissuing, by a processor, commands to said hypervisor to restore the CPU configuration of said virtual machine to only said designated CPU capacity in response to a completion of said activation of said virtual machine.
