制作ubuntu 14.04镜像

先以root用户登录：

2.编辑以dhcp的方式获取ip

[email protected]:~# vim /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp
[email protected]:~# 

重启除lo网卡的所有网卡

ifdown --exclude=lo -a && sudo ifup --exclude=lo -a

编辑/etc/ssh/sshd_config

#PermitRootLogin without-passwordPermitRootLogin yes

重启 ssh  服务

[email protected]:~# sudo service ssh restart

在/etc/apt/sources.list添加条目：

deb http://cn.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiversedeb http://cn.archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiversedeb http://cn.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiversedeb http://cn.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse

关机，编辑xml文件

virsh edit ubuntu14.04-raw<channel type=‘unix‘>      <source mode=‘bind‘ path=‘/var/lib/libvirt/qemu/org.qemu.guest_agent.0.ubuntu14.04-raw.sock‘/>       <target type=‘virtio‘ name=‘org.qemu.guest_agent.0‘/>      <address type=‘virtio-serial‘ controller=‘0‘ bus=‘0‘ port=‘1‘/></channel

注意：这个文件我在考虑要不要注释掉

<source mode=‘bind‘ path=‘/var/lib/libvirt/qemu/org.qemu.guest_agent.0.ubuntu14.04-raw.sock‘/> 

安装和配置qemu-guest-agent：

[email protected]:~# sudo apt-get update[email protected]:~# sudo apt-get install qemu-guest-agent[email protected]:~# /etc/init.d/qemu-guest-agent start[email protected]:~# /etc/init.d/qemu-guest-agent status * qemu-ga is running
