Memory management method, device, electronic device, and computer-readable storage medium

Abstract

Embodiments of the present invention disclose a memory management method, apparatus, electronic device, and computer-readable storage medium. The method includes: determining a first memory resource locked in advance and a second memory resource locked by delay; A machine operation is triggered, and a pre-lock operation is performed on the first memory resource; in response to the completion of the preset virtual machine operation, the first memory resource is released, and a delayed lock operation is performed on the second memory resource. The technical solution does not significantly increase the startup time of the virtual machine even for large-capacity memory resources, thereby improving the startup and running speed and efficiency of the virtual machine on the premise of ensuring the running quality of the virtual machine.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of resource management, and in particular, to a memory management method, apparatus, electronic device, and computer-readable storage medium. Background technique [0002] With the development of virtualization technology, KVM (Kernel-based Virtual Machine) virtualization cloud services based on VFIO (Virtual Function Input / Output Service, a user-mode driver framework) can provide users with stable and efficient pass-through virtual machines. The performance of the solution can be close to that of a physical machine, so its application is becoming more and more extensive. However, with the rise of cloud computing and artificial intelligence, the demand for storage and computing resources is increasing, and the configuration of memory capacity is increasing day by day. When using VFIO-based memory resource management, during the startup process of the virtual machine, all memory resourc...

Problems solved by technology

When using VFIO-based memory resource management, all memory resources need to be locked during the startup process of the virtual machine. Obviously, when the memory capacity is small, the memory locking process only takes a few milliseconds, and the impact on users It can be ignored, but with the increase of memory capacity, the impact of memory locking on the virtual machine startup time is increasing. For example, for a virtual machine memory configuration of 384GB, the locking of memory resources alone will take about 90 seconds. This will seriously affect the operating efficiency and quality of the virtual machine
