The invention relates to a virtual machine memory adjustment method and device. The virtual machine memory adjustment method includes: checking the memory usage of the virtual machine according to a preset memory usage threshold to determine a plurality of virtual machines whose memory needs to be adjusted; Determine the priority level of the virtual machine whose memory needs to be adjusted, and adjust the memory of the virtual machine whose memory needs to be adjusted according to the priority level of the virtual machine whose memory needs to be adjusted. According to the embodiment of the present invention, the memory of the virtual machine is adjusted according to the priority level of the memory adjustment requirement of the virtual machine, which ensures that the memory of the virtual machine deploying key applications or services is adjusted in time, and avoids the impact of priority due to untimely memory adjustment. business process.
Description
technical field [0001] The invention relates to the field of virtual machines, and more specifically, to a method and device for adjusting memory of a virtual machine. Background technique [0002] At present, virtual machine memory management in the industry generally realizes memory over-allocation (on-demand allocation), that is, first allocates a certain proportion of memory (such as 1GB) to the virtual machine according to a certain proportion according to the memory specification of the virtual machine (such as 2GB), and then according to The memory used by the virtual machine is dynamically adjusted (such as 1.5GB, 2GB) when it is running, and physical memory is allocated to the virtual machine as needed, up to the specification of the virtual machine. However, when actual physical memory resources are in short supply, different virtual machines have the same ability to allocate memory, and users with different requirements cannot be treated differently in the use of ...
