oz制作qcow2镜像

oz是一个方便制作qcow2镜像的工具，利用oz可以很方便的生成可以upload到openstack的镜像！

确保libvirtd.service和libvirt-guests.service启动！不然会出错，如果出现user,group xxxxx uid 107等错误！修改/etc/nsswitch.conf,把一下三行注释掉:
======================
passwd: files sss
shadow: files sss
group: files sss
======================
制作过程中，如果出现，guest.py,redhat.py timeout….等错误，添加参数-t 2400调大oz生成镜像的时间！
制作镜像命令：
=========================
oz-install -p -u -d3 -t 2400 -a ks.cfg centos62.tdl
=========================
如果出现虚拟机不能获取ip,删除虚拟机的/etc/udev/rules.d/70-persistent-net.rules文件！
