本文介绍了解决OpenStack中使用nova-quota-update命令时出现的HTTP500错误的方法，通过修改nova.conf配置文件启用DbQuotaDriver来实现项目的资源配额管理。

在一个云系统中，一个项目不能无限制的使用资源，必须对项目进行配额管理，在openstack中主要的命令是nova quota-update, 但是可能会提示的错误：

DEBUG (shell:740) The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-76ec703e-566e-4133-af5d-d822a6750969)

提示基本没有帮助。这里我们的原因是因为使用了fuel-web，他的默认配置文件中是不是用配额管理！在/etc/nova/nova.conf配置文件中有

quota_driver=nova.quota.DbQuotaDriver
#quota_driver=nova.quota.NoopQuotaDriver

我们必须启用DbQuotaDriver才可以，修改后执行/etc/init.d/openstack-nova-api restart即可
