ubuntu22.04按组件安装openstack yoga版阅读详情

服务器是dell r710 ，操作系统使用了ubuntu 12.04 server amd 64 ，导致了nova不能启动。

更换操作系统 ubuntu 12.04 server i386 64 后，就可以启动。（貌似不是这个原因，看下面）

按照官网，

chown -R root:nova /etc/nova

执行后，nova不能启动。原因就是root账号没有了权限。ft。。。。

nova-compute 不能启动 log 如下：

2012-05-23 17:04:45 TRACE nova Exception: Unknown connection type "None"
2012-05-23 17:04:45 TRACE nova

通过log可以看出是connection 的type 没有配置

配置文件添加如下：/etc/nova/nova.conf

--connection_type=libvirt

即可以启动
