Virtual machine specification adjustment method and apparatus

摘要

Embodiments of the present invention provide a virtual machine specification adjustment method and apparatus, where the virtual machine specification adjustment method includes: acquiring running status information of a virtual machine; determining, according to the running status information of the virtual machine, whether the virtual machine is a to-be-adjusted virtual machine; and if the virtual machine is a to-be-adjusted virtual machine, adjusting a specification of the to-be-adjusted virtual machine by using a resource in a reserved resource pool. By using the technical solutions of the present invention, efficiency of virtual machine specification adjustment is improved, thereby increasing a resource utilization rate of a data center. Setting of the reserved resource pool can ensure reliability of virtual machine specification adjustment, and can avoid, to some extent, a virtual machine specification adjustment failure due to insufficient resources, thereby increasing a success rate of virtual machine specification adjustment.

主权项

1. A virtual machine specification adjustment method implemented by a computer, comprising:
acquiring running status information of a virtual machine; determining, according to the running status information of the virtual machine, whether the virtual machine is a to-be-adjusted virtual machine; and when the virtual machine is a to-be-adjusted virtual machine, adjusting the specification of the to-be-adjusted virtual machine using a resource in a second reserved resource pool, wherein the second reserved resource pool is a reserved resource pool set according to an available resource of the virtual machine; and updating a specification of the resource in the second reserved resource pool according to a specification adjustment result of the virtual machine.
