在这台新建的虚拟机上配置，让它成为虚拟机模版(后端盘)

此时，虚拟机默认的主机名是localhost

因为是默认的最小化安装，所以很多命令是没有的，需要自己搭yum，然后安装所需软件

禁用selinux

# vi /etc/selinux/config   因为最小化安装，没有vim这个程序。但系统自带有vi，也可以修改文件

SELINUX=disabled

因为最小化安装没有vim这个程序，所以无法使用vim这个命令。如果使用vim会报错

# vim /etc/yum.repos.d/centos.repo

开启路由转发功能

# cat /proc/sys/net/ipv4/ip_forward    关闭的值是0，开启的值是1。

0

# sysctl -a | grep ip_forward       也可以这样查看它的值， sysctl -a是显示所有的内核参数

net.ipv4.ip_forward = 0

net.ipv4.ip_forward_use_pmtu = 0

如果仅仅是想临时改变某个系统参数的值，可以用2种方法来实现,例如想启用IP路由转发功能：

#echo 1 > /proc/sys/net/ipv4/ip_forward

#sysctl -w net.ipv4.ip_forward=1

以上2种方法都能立即开启路由功能，但如果系统重启，或执行了下面任意1个命令时，

# systemctl restart network

# service network restart

此时，所设置的值就会丢失。

如果想永久保留配置！！可以修改/etc/sysctl.conf文件！！！

将 net.ipv4.ip_forward=0改为net.ipv4.ip_forward=1

# cat /proc/sys/net/ipv4/ip_forward     现在的值为0，代表关闭

0

# vim /etc/sysctl.conf      追加下面这行

net.ipv4.ip_forward=1

# systemctl restart network

# cat /proc/sys/net/ipv4/ip_forward     现在的值为1，代表开启

到此，我们已经创建好了 后端盘/var/lib/libvirt/images/node.img

特别注意：后端盘是只读的，不能改动！！！

只能改前端盘！！！

点击桌面的“虚拟系统管理器”---点击了node虚拟机---右键删除，但是不要选择“删除关联的存储文件”。

之所以删去，是因为以后我们不用开启node虚拟机了。

我们只使用node虚拟机的镜像文件，以后用来创建前端盘。

-f格式是qcow2，-b是用后端盘镜像文件node.img，创建前端盘镜像文件openstack.img，大小50G

# qemu-img create -f qcow2 -b node.img openstack.img 50G

显示如下：

Formatting 'openstack.img', fmt=qcow2 size=53687091200 backing_file='node.img' encryption=off cluster_size=65536 lazy_refcounts=off

可以查看前端盘镜像文件openstack.img的具体信息

# qemu-img info openstack.img
