ovirt 虚拟机使用nat上网

前提条件ovirt引擎装好了,下面的环境vdsm和engine是装在同一台服务器上

1.创建NAT网络配置文件/etc/libvirt/qemu/networks/nat.xml,内容如下

cd   /etc/libvirt/qemu/networks

cp default.xml nat.xml

vim nat.xml

 2.通过libvirt/virsh创建NAT网络

[root@engine networks]# virsh
Welcome to virsh, the virtualization interactive terminal.

Type: 'help' for help with commands
'quit' to quit

virsh # connect qemu:///system
Please enter your authentication name: vdsm@ovirt
Please enter your password:shibboleth

virsh # net-list
Name State Autostart Persistent
----------------------------------------------------------
;vdsmdummy; active no no
nat active no no

virsh # net-define /etc/libvirt/qemu/networks/nat.xml

virsh # net-autostart nat1
Network nat1 marked as autostarted

virsh # net-start nat1
Network nat1 started

virsh # net-list --all
Name State Autostart Persistent
----------------------------------------------------------
;vdsmdummy; active no no
default inactive no yes
nat active no no
nat1 active yes yes

yum install -y vdsm-hook-extnet

[root@engine packages]# engine-config -s CustomDeviceProperties='{type=interfac e;prop={extnet=^[a-zA-Z0-9_ ---]+$}}'
Please select a version:
1. 4.1
2. 4.2
3. 4.3
3

 engine-config  -g  CustomDeviceProperties

systemctl restart ovirt-engine

点击vnic配置集,然后新建

 编辑虚拟机，重新选择vnic，选择刚刚新建的

开机测试，实验完成
