Notes on Ubuntu virtualization technology

Ubuntu is about Ubuntu 7.10 (or ?) The introduction of virtualization technology is called KVM, and KVM is the Kernel-basedVirtualMachine, which is not related to Ubuntu. This Is A virtualization technology supported by Linux Kernel, but the Linux Kernel used by Ubuntu7.04 exactly supports KVM. In Ubuntu, as we all know, there are VMware and VirtualBox desktop virtual machines. In fact, another option is KVM.

Ubuntu is about Ubuntu 7.04 (or 7.10 ?) The introduction of virtualization technology is called KVM. KVM is a Kernel-based Virtual Machine, which is not related to Ubuntu. This is a Linux Kernel-level virtualization technology, but it happens that the Linux Kernel used in Ubuntu 7.04 supports KVM. In Ubuntu, as we all know, there are VMware and VirtualBox desktop virtual machines. In fact, another option is KVM. As long as your CPU supports CPU Hardware virtualization technology, you can use KVM. Most mainstream AMD desktop CPUs on the market, such as AMD Athlon64 × 2 4000 + or more advanced products, support AMD-V, some Intel products may not support virtualization technology (Intel VT), so we need to use commands to check whether the CPU used supports virtualization. This is the premise of using KVM virtualization technology:
