Abstract

The invention relates to the technical field of memory management, in particular to a memory overconfiguration management method and device. The method is applied to a first service host in a cluster, the cluster further comprises a plurality of other service hosts and a management host, and the method comprises the steps: when it is determined that the local memory usage amount is larger than or equal to a set threshold value, sending a notification to the management host, enabling the management host to query the memory use conditions of the other service hosts in the cluster, and determining a second service host of which the memory use amount meets a preset requirement based on the memory use conditions of the other service hosts; receiving the second service host information sent by the management host; and establishing a remote direct memory access connection with the second service host based on the second service host information, and applying for a memory pool from the second service host.

Description

technical field [0001] The present application relates to the technical field of memory management, in particular to a memory over-allocation management method and device. Background technique [0002] In the field of cloud computing, virtual machine memory over-allocation means that the sum of the memory capacity of multiple virtual machines exceeds the sum of the physical memory of the host machine. The reason for over-allocation is that the virtual machine may not actually use the configured memory completely. Over-allocation can improve the utilization of system resources. [0003] The problem with over-allocation of virtual machine memory is that when the server system memory is insufficient, it will cause insufficient virtual machine memory and cause system problems. [0004] Currently, the solution to the over-allocation problem is to use the host's swap space to expand memory. [0005] Under Linux, the function of swap is similar to the "virtual memory" under Windo...
