Memory processing method and device, electronic equipment and readable medium

Abstract

The invention provides a memory processing method and device, electronic equipment and a readable medium, in the method, a host machine connected with external equipment determines the current allocated memory amount according to the current allocated memory of the virtual machine for any virtual machine. The currently allocated memory is the memory, which can be directly accessed by the external equipment, in the virtual machine memory of the virtual machine. And when the current allocated memory amount is not less than a preset memory amount threshold value, cancelling the allocation of the specified memory page in the allocated memory. Wherein the preset memory capacity threshold value is not greater than the virtual machine memory of the virtual machine. Therefore, all memories of the virtual machine can be prevented from being distributed, and the problem that the processing performance of the host machine is influenced under the condition that the memory of the host machine is insufficient can be avoided to a certain extent.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic devices, and in particular, to a memory processing method, apparatus, electronic device, and readable medium. Background technique [0002] With the continuous development of network technology, virtual machines have been used more and more. When using a virtual machine, in order to facilitate the external device to access the memory of the virtual machine in the host machine, the external device needs to be directly connected to the virtual machine. [0003] In the existing method, when device passthrough is performed, all the memory of the virtual machine is allocated to the external device, so that the external device can access the memory of the virtual machine. In this way, the processing performance of the host will be affected when the host memory is tight. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a memory processing method,...
