What are the virtualization technologies in Linux?

Common virtualization technologies in the Linux system include:

1. KVM, which stands for Kernel-based Virtual Machine, is a module in the Linux kernel that turns Linux systems into a comprehensive virtualization platform, enabling the creation, management, and operation of virtual machines.
2. Xen is an open-source virtualization software that allows multiple virtual machines to run simultaneously on one physical server, and it can also achieve hardware virtualization.
3. VirtualBox is an open-source virtualization software that allows multiple client operating systems to run on a Linux system, supporting a variety of different operating systems.
4. Containerization technology like Docker allows for the rapid deployment, execution, and management of applications on Linux systems, ultimately leading to improved system resource efficiency.
5. LXC (Linux Containers): LXC is a container technology in Linux systems that packages applications and their dependencies into a container for lightweight virtualization.
6. QEMU is an open-source virtual machine monitor and emulator that can simulate various hardware platforms and processor architectures on Linux systems.
