Common VPS environment architecture (XEN, OpenVZ, KVM, Hyper-V, HVM)

The commonly used VPS environments on the market are: XEN, OpenVZ, KVM, Hyper-V, HVM, etc.
1. OpenVZ architecture: Based on the Linux operating system, it can only support the Linux operating system. The allocated chicks are also Linux, and do not support Windows. OpenVZ supports overselling technology. The mother hen has 2G memory and can be divided into 10 512-memory chicks. Hard drives, etc. are also acceptable. Foreign IDCs like to use it. Features: low price. Domestic overselling technology does not meet foreign standards, so it is rarely used in China.
2. XEN architecture: Complete hardware partitioning, can support Linux and Windows operating systems; does not support overselling, if you want to partition out chickens, you must have sufficient hardware resources. Relatively speaking, XEN's chicken is more stable to use. Its characteristics are: more expensive and more popular among Chinese IDCs.
3. KVM architecture: requires VNC connection, automatic upload or loading of ISO files, and the operating system needs to be installed by yourself. Relatively speaking, there is more freedom and customization, but it is also more troublesome, and most webmasters hate trouble.
4.Hyper-V architecture is based on Microsoft's system.
