我安装了Microstack，我试图Openstack用我在互联网上找到的糟糕的文档来理解它的操作。我试图访问一些已启动的虚拟机但没有成功。Microstack已经创建了以下两个网络：
microstack.openstack network list
+--------------------------------------+----------+--------------------------------------+
| ID | Name | Subnets |
+--------------------------------------+----------+--------------------------------------+
| 750286d8-2801-4dd3-85d8-85b0e4219b46 | test | fbe5a4e4-34c7-4b39-a4e5-a447431d78dc |

下面，我列出了用于启动 VM 的安全组：
microstack.openstack security group show 3c69498c-c210-48c8-ba43-fbf60a0c224e

我已经启动了两个Ubuntu具有可用网络 (test和external) 的 VM，如下所示：
microstack.openstack server list
+--------------------------------------+-------------+--------+-----------------------------------+-------------+-----------+
| ID | Name | Status | Networks | Image | Flavor |
+--------------------------------------+-------------+--------+-----------------------------------+-------------+-----------+
| 4bd80f7c-8c16-4b15-9973-887f0f2517ff | test1 | ACTIVE | external=10.20.20.197 | ubuntu_1804 | m1.medium |
| ca2e690e-e679-4fd7-a507-07f12bcf1c5e | test2 | ACTIVE | test=192.168.222.141 | ubuntu_1804 | m1.medium |
这是用于启动 VM 的命令：
microstack.openstack server create --flavor m1.medium --image ubuntu_1804 \
--nic net-id=e9d9520f-3ad7-4f96-bff5-060beb1c0161 --key-name mykey \
--security-group 3c69498c-c210-48c8-ba43-fbf60a0c224e test1
然后，当我尝试访问两个启动的虚拟机时，我得到Destination Host Unreachable：
ping 10.20.20.197
PING 10.20.20.197 (10.20.20.197) 56(84) bytes of data.
From 10.20.20.1 icmp_seq=1 Destination Host Unreachable
ping 192.168.222.141
PING 192.168.222.141 (192.168.222.141) 56(84) bytes of data.
From 192.168.131.133 icmp_seq=1 Destination Host Unreachable
谁能解释一下我错过了什么？
