Abstract

The embodiment of the invention provides a virtual machine management method and system. The method comprises the following steps: firstly, a management client in a virtual machine manager sends a virtual machine management request through a second direct connection port, and a kernel server receives the virtual machine management request through a first direct connection port; then the kernel server manages the virtual machine based on the virtual machine management request to generate a virtual machine management result; and the kernel server sends the virtual machine management result to the management client through the first direct connection port. Based on the first direct connection port and the second direct connection port, an efficient management channel is provided; according to the method, the kernel server in the user mode is moved into the kernel of the client to form the kernel server in the kernel mode, so that the link between the management client and the kernel of the client is shortened, the management link of the virtual machine is shortened, the stability of the kernel of the client is improved, and privileged operation can be performed based on the kernel mode of the kernel server; and the management efficiency of the virtual machine is improved.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular to a virtual machine management method. Background technique [0002] With the rapid development of computer technology, secure containers have been widely used. At present, secure containers have been applied in many project scenarios in the cloud-native field and become an indispensable basic component. A secure container is a container that supports kernel isolation technology. Compared with ordinary containers, it has its own kernel. Since secure containers are based on hardware virtualization technology, each container or container group has an independent operating system kernel, so a control channel is required to complete some virtual machine management tasks, such as adding and deleting devices, configuring resource elasticity, and so on. A traditional virtual machine manager (VMM, Virtual Machine Manager) needs to complete corresponding opera...
