环境说明

操作系统镜像：ubuntu-22.04.1-live-server-amd64.iso

可以直接去官网下载Get Ubuntu Server | Download | Ubuntu

宿主机OS使用的是最小化安装ubuntu-22.04

参考如下链接执行：

Ubuntu 22.04 之 KVM 安装手札-ubuntu20.04安装kvm

更新 Ubuntu 22.04
检查虚拟化是否开启

3、在 Ubuntu 22.04 上安装 KVM

sudo apt install -y qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils

参考链接：

KVM hypervisor: a beginners’ guide | Ubuntu

Install KVM Ubuntu 22.04 - Step-by-Step - Virtualization Howto

创建虚拟网桥

sudo virsh net-define /dev/stdin <<EOF
<network>
  <name>virbr0</name>
  <forward mode="bridge"/>
  <bridge name="virbr0"/>
</network>
EOF
sudo virsh net-start virbr0
sudo virsh net-autostart virbr0

4、创建 KVM虚拟机

virt-install --name=k8s01 --ram 1024 --vcpus=2 --disk path=~/k8s01.img,size=30 --accelerate --cdrom ~/CentOS-7-x86_64-DVD-2009.iso

virt-install --name=k8s02 --ram 1024 --vcpus=2--disk path=~/k8s02.qcow2,size=10,format=qcow2,bus=virtio --location=~/CentOS-7-x86_64-DVD-2009.iso --network network=default,model=virtio --graphics=none --console=pty,target_type=serial --extra-args="console=tty0 console=ttyS0"

5、登录 KVM虚拟机

virt-viewer --connect qemu:///system --wait k8s01

使用virsh-manager基于iso创建虚拟机

$ sudo apt install -y virt-manager

$ virt-manager

$ virsh shutdown ubuntu22.04

Domain 'ubuntu22.04' is being shutdown

$ virsh list --all

Id Name State

------------------------------

- ubuntu22.04 shut off
