開啓路由轉發功能
# cat /proc/sys/net/ipv4/ip_forward 關閉的值是0，開啓的值是1。

# sysctl -a | grep ip_forward 也能夠這樣查看它的值， sysctl -a是顯示全部的內核參數
net.ipv4.ip_forward = 0
net.ipv4.ip_forward_use_pmtu = 0
若是僅僅是想臨時改變某個系統參數的值，能夠用2種方法來實現,例如想啓用IP路由轉發功能：
#echo 1 > /proc/sys/net/ipv4/ip_forward
#sysctl -w net.ipv4.ip_forward=1
以上2種方法都能當即開啓路由功能，但若是系統重啓，或執行了下面任意1個命令時，
# systemctl restart network
# service network restart
此時，所設置的值就會丟失。
若是想永久保留配置！！能夠修改/etc/sysctl.conf文件！！！
將 net.ipv4.ip_forward=0改成net.ipv4.ip_forward=1
# cat /proc/sys/net/ipv4/ip_forward 如今的值爲0，表明關閉

# vim /etc/sysctl.conf 追加下面這行

# systemctl restart network
# cat /proc/sys/net/ipv4/ip_forward 如今的值爲1，表明開啓

到此，咱們已經建立好了 後端盤/var/lib/libvirt/images/node.img
特別注意：後端盤是隻讀的，不能改動！！！
只能改前端盤！！！
點擊桌面的「虛擬系統管理器」---點擊了node虛擬機---右鍵刪除，可是不要選擇「刪除關聯的存儲文件」。
之因此刪去，是由於之後咱們不用開啓node虛擬機了。
咱們只使用node虛擬機的鏡像文件，之後用來建立前端盤。

真機
-f格式是qcow2，-b是用後端盤鏡像文件node.img，建立前端盤鏡像文件openstack.img，大小50G
# qemu-img create -f qcow2 -b node.img openstack.img 50G
顯示以下：
Formatting 'openstack.img', fmt=qcow2 size=53687091200 backing_file='node.img' encryption=off cluster_size=65536 lazy_refcounts=off
能夠查看前端盤鏡像文件openstack.img的具體信息
# qemu-img info openstack.img
顯示以下：
