Use KVM high performance to create virtual images in Linux systems

1. Introduction This article uses KVM on Debian12 system to implement virtual image management through graphical interface and command line. KVM is an open source virtualization technology embedded in the Linux kernel. It can transform a Linux system into a hypervisor, allowing the host computer to run multiple isolated virtual environments. Compared with other commercial […]

Four simple network models in KVM

The four simple network models in KVM are as follows: 1. Isolation model (QEMU’s built-in user mode networking): A network is established between virtual machines. This mode cannot communicate with the host or other networks. It is equivalent to the virtual machine just being connected to a switch. . 2. Routing model (direct allocation of […]

KVM virtualization ubuntu

KVM (Kernel-based Virtual Machine) is a virtualization technology based on the Linux kernel. It uses the Linux kernel as the underlying operating system of the virtual machine and uses hardware virtualization to support the creation and management of virtual machines. KVM virtualization technology is widely used in cloud computing, virtualized servers, virtualized desktops and other […]
