On the whole, this technology occupies a leading position in the core, and its advanced nature is obvious. The emergence of VR socialization, VR shopping, VR games, VR conferences, VR fitness, VR virtual conference rooms, etc. , a good solution to the dilemma of insufficient computer hardware resources, and with the continuous development and improvement of technology, virtualization technology has the characteristics of safety, reliability and high utilization rate, which further improves the application level of the server and improves the service effect. At present, virtualization technology is mainly divided into three aspects, namely complete virtualization, partial virtualization and operating system virtualization. According to different levels of abstraction, virtual technology can be divided into five levels: hardware layer, instruction layer, programming language layer, operating system layer and runtime layer. There are differences among the five levels, but in essence, they all allocate resources reasonably to the upper level for use.

The software named "Wei" was developed on the basis of the meta-universe. VR virtual conference room not only allows people to work remotely and efficiently, but also allows people to share screens, videos and files and draw pictures on the screen, so many people can enjoy discussing topics together. But also you can build cities, factories and so on by yourself. Not only can you quickly build scenes, edit models and 3D renderings, but you can also roam in VR.

2. Application status of network security monitoring technology in virtualized environment.

At present, the application of network security monitoring technology in virtualized environment is widely accepted and valued. With the deepening of application, the amount of data in the network is increasing and the importance is getting higher and higher. With the improvement of the functionality and convenience of the network system, there are also some system factors that can threaten the security of data and information. The traditional network security monitoring technology is slow to update, and its adaptive ability is insufficient, so it is difficult to filter or defend the current threats, which makes the network security monitoring technology exist in name only and cannot play a good role in security monitoring. The application of network security monitoring technology in virtualized environment solves the shortcomings of traditional network security monitoring technology, and its powerful information and data analysis ability enables network security monitoring technology in virtualized environment to adapt to users, thus continuously improving the filtering and defense level of network threats. Firewall and intrusion detection technology are both specific application forms based on network security monitoring technology in virtualized environment. When designing the application of network security monitoring technology in virtual environment, we should follow the principle of safety and effectiveness to prevent virtual managers from appearing loopholes or being attacked by the outside world. Specifically, the application of network security monitoring technology in virtualized environment can be divided into internal and external aspects. Among them, the internal monitoring is mainly aimed at intercepting abnormal events in the kernel module, and the virtual manager manages multiple virtual machines to load the kernel to ensure absolute network security. External monitoring emphasizes the rational use of virtual machines to improve the interception effect of abnormal events and the detection efficiency of abnormal events.
