Abstract

Embodiments of the present application provide a device direct connection method, device, and storage medium for a virtual machine. In the pass-through method of virtual machine devices, when a virtual machine uses the first protocol to access a device that conforms to the second protocol on the host, it can be determined that the access request of the virtual machine is in the second protocol according to the semantic correspondence between the first protocol and the second protocol. The corresponding access under the specification. Based on the access mode specified by the second protocol, the device conforming to the second protocol can be accessed. Furthermore, when the protocol followed by the device provided by the host is different from the protocol adopted by the driver of the virtual machine, the direct connection between the virtual machine and the device on the host can be flexibly realized without adding a protocol followed by the device in the virtual machine The corresponding driver helps the virtual machine to be more streamlined and lightweight.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular to a device-through method, device and storage medium for a virtual machine. Background technique [0002] During the development of cloud native, secure containers have gradually become the focus of attention, and security sandboxes (sandbox) have been widely used. The security sandbox can meet cloud-native container standards and provide users with a secure runtime environment. At the same time, the security sandbox occupies less resources and has a faster startup speed. [0003] In some existing security sandboxes, a virtual machine cannot flexibly communicate directly with a device provided by a host, so that the virtual machine cannot achieve performance equivalent to that of a physical device. Therefore, a solution remains to be proposed. Contents of the invention [0004] Aspects of the present application provide a device direct connection method, ...
