10. 在CentOS 6.3上通过源码安装Openstack Folsom之通过Glance上传镜像
11. 在CentOS 6.3上通过源码安装Openstack Folsom之通过Horizon启动实例

错误修复
1. 删除/etc/quantum/quantum.conf文件中添加的sed -i '14a log_dir = /var/log/quantum' /etc/quantum/quantum.conf
2. 删除/etc/quantum/quantum.conf文件中添加的sed -i '15a log_file = quantum.log' /etc/quantum/quantum.conf
3.修正：
    net_id=`quantum net-create --tenant-id $put_id_of_project_one net_one --provider:network_type flat --provider:physical_network physnet1 |awk '/ id/ {print $4}'`
   为
   net_id=`quantum net-create --tenant-id $tenant_id net_one --provider:network_type flat --provider:physical_network physnet1 |awk '/ id/ {print $4}'`

4. 去除修改/etc/quantum/quantum.conf文件的如下一些选项中的：
    sed -i 's/# default_notification_level = INFO/default_notification_level = DEBUG/g' /etc/quantum/quantum.conf

系统环境

1. CentOS 6.3 x86_64
   
2. Openstack Folsom
   
3. 服务器IP：172.16.24.138
   
4. 注：因为用到了Quantum，系统需要至少两块网卡
   
5. 这里使用的flat+dhcp模式，类似于nova-network的flatmanager模式，所以网段最好跟物理机网段一致，后面会单独发帖讲解gre和local还有vlan模式

我觉得楼主可以暂时建立一个群，方便我们这些人在里面询问，相互讨论一下，而且你还有6篇没有写完，这样在论坛上面提问题的做事效率也太慢了
