使用virt
小伙伴们好不容易的把openstack环境部署好了；默认会有一个ubuntu系统的镜像，如果想使用centos或者是其它的系统怎么办呢？那么接下就是制作咯；如果你会制作一个任意系统只要是openstack能支持的就行，这样就不用担心没有系统资源的问题了；如果在安装配置virt-manager有问题，请看我之前发布的文章；
前提准备：
系统镜像：centos6
虚拟磁盘：virtual_disk
创建虚拟磁盘：
qemu-img create -f qcow2 centos6.img 10G 运行
# virt-manager 打开Virtual Machine Manaer图形界面；

这个还可以监控vm的cpu，内存等信息；

完成重新启动一下！
删除网络配置
删除ifcfg-eth0的HWADDR一行，最后你的ifcfg-eth0的配置文件应该是这样的：
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="dhcp"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
删除已生成的网络设备规则
rm -rf /etc/udev/rules.d/70-persistent-net.rules
关闭防火墙和selinux
sed -i s/^SELINUX=.*/SELINUX=disabled/g /etc/selinux/config
service iptables stop && chkconfig iptables off
service ip6tables stop && chkconfig ip6tables off
