一 安装KVM
1、Check CPU是否支持虚拟化，输出vmx或svm则支持。
[root@kvmhost001 xml]# cat /proc/cpuinfo | egrep 'vmx|svm'

[root@kvmhost001 xml]#2、查看系统版本
[root@kvmhost001 xml]# cat /etc/centos-release
CentOS Linux release 7.7.1908 (Core)
[root@kvmhost001 xml]#3、查看是否加载KVM
[root@kvmhost001 xml]# lsmod | grep kvm
kvm_intel 188644 0
kvm 621480 1 kvm_intel
irqbypass 13503 1 kvm
[root@kvmhost001 xml]#如上显示则已加载，否则执行如下命令：
[root@kvmhost001 xml]# modprobe kvm4、关闭selinux
<可选>
5、安装KVM相关软件包
[root@kvmhost001 xml]# yum install qemu-kvm qemu-img \
virt-manager libvirt libvirt-python virt-manager \
libvirt-client virt-install virt-viewer -yqemu-kvm: KVM模块
libvirt: 虚拟管理模块
virt-manager: 图形界面管理虚拟机
virt-install: 虚拟机命令行安装工具
[root@kvmhost001 xml]# yum install qemu-kvm qemu-img \
> virt-manager libvirt libvirt-python virt-manager \
> libvirt-client virt-install virt-viewer -y

6、给系统做一个快照，中途出现问题方便重置
二 配置KVM
1、使用Virtual Machine Manager工具配置虚拟机的运行环境
虚拟网络设定
虚拟机存储设定
网络接口
尝试创建个新的桥接网络；如果向导中创建不了；则使用下面的指令执行：
因此我们需要通过命令创建一个虚拟网络并桥接到上文中双网卡绑定的网卡上。
2、配置网卡
# 网卡配置，新建ifcfg-br001，然后修改相关配置如下：
[root@kvmhost001 xml]# cd /etc/sysconfig/network-scripts/
[root@kvmhost001 network-scripts]# vi ifcfg-br001
[root@kvmhost001 network-scripts]# cat ifcfg-br001

注意br001这块虚拟的桥接卡的配置信息。
重启计算机。
三 安装并管理虚拟机
1、创建虚拟机
2、我们先上传个镜像到/KVM_ISO
3、New VM
4、分配内存
5、创建虚拟磁盘
6、设置虚拟机名字和网络
7、检查并确认虚拟机的设定是否是自己想要的；如果不符合需求，这里还可以进行修正。
8、开始安装OS
OS的安装过程就省略了。
因为我没有为桥接的网卡配置DHCP所以我们还需要手动设置下IP地址。
9、创建虚拟环境快照：
[root@tempsrv01 ~]# virsh list
Id Name State
----------------------------------------------------
4 tempsrv02 running
[root@tempsrv01 ~]# virsh snapshot-create tempsrv02
Domain snapshot 1618280605 created
[root@tempsrv01 ~]# virsh snapshot-list tempsrv02
Name Creation Time State
------------------------------------------------------------
1618280605 2021-04-13 10:23:25 +0800 running
[root@tempsrv01 ~]#
四 虚拟机的基础设定
1、配置网卡
注意onboot=yes；否则重启后网卡不会自动启动。
有可能出现ping不通网关的情况：
好了，本文就到这里；喜欢的朋友请三连哦。
