1 您需要了解
- 约定：我们称运行在
VMware Workstation里面的虚拟机为客户虚拟机（以下简称虚机，采用CentOS 7.8图形化）；我们称在虚机里面基于KVM运行的虚拟机为KVM虚拟机（以下简称KVM虚机，采用CentOS 7.4），是的，两层套娃 虚机在启动前，必须在VMware Workstation上为其开启虚拟化引擎虚拟化 Intel VT-x/EPT 或 AMD-V- 建议
虚机网络配置为NAT或桥接，因为未来KVM虚机需要借助虚机的外网能力进行联网安装软件包 - 您可参考下列相关文章

2 安装 KVM 虚机
2.1 虚机安装虚拟化软件包
#配置本地YUM源
[root@cloudcs ~]# mkdir /tmp/repo
[root@cloudcs ~]# mv /etc/yum.repos.d/*.repo /tmp/repo/
[root@cloudcs ~]# vim /etc/yum.repos.d/local.repo
[root@cloudcs ~]# cat /etc/yum.repos.d/local.repo
[local_repo]
name = local
baseurl = file:///mnt/
gpgcheck = 0
#安装虚拟化软件包及虚拟机镜像管理工具
[root@cloudcs ~]# yum groupinstall -y "Virtualization*"
[root@cloudcs ~]# yum install -y libguestfs-tools-c.x86_64
## 2.2 创建 KVM 虚机
> 注意：`虚机` 通过命令 `ifconfig` 可看到一张虚拟网卡 `vritbr0`，该虚拟网卡为 `kvm虚机` default 默认的 `NAT` 网络类型网卡（`192.168.122.1`）
```shell
#创建目录上传ISO镜像
[root@cloudcs ~]# mkdir -p /soft/disk
#将 CentOS 7.4 上传到 /soft 目录下
[root@cloudcs ~]# ls /soft/
CentOS-7-x86_64-DVD-1708.iso disk
#创建 kvm虚机 使用的磁盘文件
[root@cloudcs ~]# qemu-img create -f qcow2 /soft/disk/centos7.qcow2 15G
Formatting /soft/disk/centos7.qcow2, fmt=qcow2 size=16106127360 encryption=off cluster_size=65536 lazy_refcounts=off
#创建 kvm 虚机
virt-install \\
--name centos \\
--disk path=/soft/disk/centos7.qcow2 \\
--vcpus 1 \\
--memory 2048 \\
--location /soft/CentOS-7-x86_64-DVD-1708.iso \\
--network network=default2.3 安装 KVM 虚机
2.3.1 语言选择
2.3.2 自动分区
2.3.3 网络及主机名
2.3.4 配置 ROOT 密码
2.3.5 重启并测试网络
3 配置 KVM 虚拟机
3.1 修改 KVM 虚机网络配置文件
# 修改 kvm 虚机网卡配置文件，使其只包括以下 4 行内容
[root@local ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
[root@local ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=dhcp
DEVICE=eth0
ONBOOT=yes3.2 安装 cloud-init 软件包
[root@local ~]# yum install -y cloud-utils-growpart cloud-init
#输出
