因上管理节点nova.conf配置文件中修改了instances实例存放的位置，还需要作一下操作：
修改路径，设置目录权限：
[root@node ~]# cp -r /var/lib/nova/ /openstack/lib/
[root@node ~]# chown -R nova:nova /openstack/lib/nova/
(3).启动nova相关服务，设置开机自启动 [root@node ~]# service messagebus start [root@node ~]# chkconfig messagebus on
[root@node ~]# service openstack-nova-compute start [root@node ~]# service openstack-nova-network start [root@node ~]# chkconfig openstack-nova-compute on [root@node ~]# chkconfig openstack-nova-network on

OpenStack其他常用命令：
1.list nova服务，包含管理节点和计算节点 [root@openstack ~]# nova service-list

2.查看计算节点：
[root@node ~]# nova hypervisor-list +----+---------------------+ | ID | Hypervisor hostname | +----+---------------------+ | 1 | openstack | | 2 |node | +----+---------------------+
3.查看虚拟机模板配置：
[root@node ~]# nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
