Abstract

The invention discloses a memory resource management method and device. It involves virtual machine technology, which solves the problem of interrupting customer service caused by releasing memory through restart. The method includes: acquiring the internal memory usage of the virtual machine; acquiring the physical memory occupation occupied by the virtual machine process; and performing memory release when the memory usage and the physical memory occupation reach a preset memory release condition. The technical solution provided by the invention is suitable for a virtual machine management platform, and realizes automatic execution of memory release.

Description

technical field [0001] The invention relates to virtual machine technology, in particular to a memory resource management method and device. Background technique [0002] During the operation of the Linux virtual machine created by Libvirt and Qemu, the occupied memory will gradually increase with the increase of the internal business volume of the virtual machine. When the business volume decreases, the internal memory usage of the virtual machine will gradually decrease, but the host The memory occupied by the corresponding Qemu process above will not decrease, that is, the memory occupied by Qemu will not be released, resulting in less and less available memory on the host and more and more tight resources. [0003] Generally speaking, to change the host memory occupied by the client, you must first shut down the client, modify the memory configuration at startup, and then restart the client. This requires interruption of customer service and affects the user experience....
