使用oz制作镜像

1、安装软件包

# rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm

# yum install -y oz libguestfs-tools

2、修改配置文件（默认即可）

需要注意的是，制作出来的镜像，不管是raw格式还是qcow2格式，都是不经过压缩的，具体往下看

 # cat /etc/oz/oz.cfg 

[paths]
output_dir = /var/lib/libvirt/images
data_dir = /var/lib/oz
screenshot_dir = /var/lib/oz/screenshots
# sshprivkey = /etc/oz/id_rsa-icicle-gen

[libvirt]
uri = qemu:///system
image_type = qcow2
#image_type = raw
# type = kvm
# bridge_name = virbr0
# cpus = 1
# memory = 1024

[cache]
original_media = yes
modified_media = no
jeos = no

[icicle]
safe_generation = no

3、定义tdl文件

cat centos6.6.ks
