What this article shares with you is about what the cpu1 core of the virtual host is. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.
In fact, the concept of virtual host cpu 1 core is not accurate, because virtual host is a part of the space split on the server, it is a shared resource, and there is no independent CPU. Therefore, the saying of 1-core CPU is common in cloud servers or stand-alone servers.
The virtualization technology of CPU, which can simulate multi-CPU parallelism with a single CPU, allows a platform to run multiple operating systems at the same time, and applications can run in independent spaces without affecting each other, thus significantly improving the efficiency of computers.
There are multiple programs running in each operating system, and each operating system runs on a virtual CPU or virtual space, while hyper-threading technology is only a single CPU simulation of double CPU to balance program performance, the two simulated CPU can not be separated and can only work together.
The virtualization technology of CPU is a hardware scheme. CPU, which supports virtual technology, has specially optimized instruction sets to control the virtual process. Through these instruction sets, VMM can easily improve the performance. Compared with the virtual implementation of the software, it will greatly improve the performance. Virtualization technology provides chip-based capabilities, and pure software solutions can be improved with compatible VMM software.
Therefore, the general parameter standard of virtual host is web space. Even if only CPU supports virtualization technology, it will have better performance with VMM software than systems that do not support virtualization technology at all.
The above is what the virtual host cpu1 core is, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
