这个时候eth0，已经没有具体的IP地址。IP地址出在了br0的虚拟网上面。
我们ping一下公网ip，看看是不是通的。
~ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

4. 创建虚拟机
通过virt虚拟机管理软件，创建虚拟机(Guest)。
上传2个安装镜像到Server: u1204.iso, xp.iso
放在/home/conan/os目录下面。
1)创建Guest1, Ubuntu 64位LTS 12.04版本(命令行，无可视化界面)
把u1204.iso文件mount一个目录
~ sudo mount -o loop /home/conan/os/u1204.iso /home/conan/os/ubuntu
~ ls /home/conan/os/ubuntu
boot dists EFI isolinux pics preseed ubuntu
cdromupgrade doc install md5sum.txt pool README.diskdefines
创建虚拟机
~ sudo virt-install --connect=qemu:///system \
--name g1 \
--ram 2048 \
--vcpus=2 \
--os-type=linux \
--os-variant=ubuntuprecise \
--accelerate \
--hvm \
--disk path=/home/conan/os/g1.img,size=6,bus=virtio \
--location /home/conan/os/ubuntu \
--extra-args='console=tty0 console=ttyS0' \
--network bridge=br0,model=virtio \
--graphics none

安装完成
2). 创建Guest2, Ubuntu 64位LTS 12.04版本(通过VNC，有可视化界面)
在server端，我要打开vnc_listen的端口支持
~ vi /etc/libvirt/qemu.conf
#打开注释
vnc_listen="0.0.0.0"
重启virt软件
~ sudo /etc/init.d/libvirt-bin restart
~ netstat -nlt|grep 5900
tcp 0 0 0.0.0.0:5900 0.0.0.0:* LISTEN
我们需要使用到Xming和putty配合，可以让putty远程传输的VNC信号通过Xming显示出来。
在putty里面，我们要修改一下配置。
启动Xming软件
执行命令
