Abstract

The embodiment of the invention relates to the technical field of computers, in particular to a capacity changing method and device for a virtual machine, which are used for solving the problem that the service continuity cannot be ensured when the capacity of the virtual machine is changed. The method comprises the steps: receiving a virtual machine capacity change reques, whereinthe virtual machine capacity change request is a thermal expansion request or a thermal shrinkage request, and the virtual machine capacity change request comprises a virtual machine identifier and a change capacity;determining that the state of the virtual machine is normal operation according to the virtual machine identifier; obtaining the current capacity of the virtual machine and the specification of a physical machine where the virtual machine is located; according to the change capacity and the current capacity of the virtual machine and the specification of the physical machine, determining the feasibility of the change capacity; and when the feasibility of changing the capacity is yes, setting the capacity of the virtual machine from the current capacity to the changed capacity.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for changing the capacity of a virtual machine. Background technique [0002] A virtual machine refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Everything that can be done on a physical computer can be done on a virtual machine. When creating a virtual machine on a computer, part of the hard disk and memory capacity of the physical machine needs to be used as the hard disk and memory capacity of the virtual machine. Each virtual machine has an independent CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor), hard disk and operating system, and the virtual machine can be operated like a physical machine. [0003] Under normal circumstances, the capacity of the virtual machine is sufficient to ensure the normal opera...
