nova list用于在shell交互模式下查看当前用户存在的实例数目，但是这里仍然要注意的地方：

没有参数的nova list

[root@node-5 newstest-master]# nova list
+--------------------------------------+-------+--------+------------+-------------+-----------------------------------------------------------------+
| ID                                   | Name  | Status | Task State | Power State | Networks                                                        |
+--------------------------------------+-------+--------+------------+-------------+-----------------------------------------------------------------+
| b3738b0a-8a27-4720-8364-503543fbb13c | test2 | ACTIVE | None       | Running     | network_20=10.10.0.3; test_pool=10.20.0.3; novanetwork=10.0.0.2 |
+--------------------------------------+-------+--------+------------+-------------+-----------------------------------------------------------------+
[root@node-5 newstest-master]# nova list

有参数nova list --all-tenants 1

[root@node-5 newstest-master]# nova list --all-tenants 1
+--------------------------------------+-------+--------+------------+-------------+-----------------------------------------------------------------+
| ID                                   | Name  | Status | Task State | Power State | Networks                                                        |
+--------------------------------------+-------+--------+------------+-------------+-----------------------------------------------------------------+
| 957b3fd5-0526-4e23-a4f6-bbeb5a9cd734 | 1     | ACTIVE | None       | Running     | network_20=10.10.0.4; test_pool=10.20.0.4; novanetwork=10.0.0.4 |
| b3738b0a-8a27-4720-8364-503543fbb13c | test2 | ACTIVE | None       | Running     | network_20=10.10.0.3; test_pool=10.20.0.3; novanetwork=10.0.0.2 |
+--------------------------------------+-------+--------+------------+-------------+-----------------------------------------------------------------+

从这里我们可以看到，如果不指定参数要求获取全部的实例列表，那么当前获得实例列表将使当前的项目的list.
