openstack【Kilo】入门 【网络篇】十七：创建实例

问题导读

1.创建实例需要哪些条件?
2.创建实例使用的是哪个网络ID？
3.如何不安装dasboard，访问创建实例？







1.生效认证
[mw_shl_code=bash,true]source demo-openrc.sh[/mw_shl_code]

2.生成并添加一个密钥对：

[mw_shl_code=bash,true]nova keypair-add demo-key[/mw_shl_code]

3.验证密钥对
[mw_shl_code=bash,true]nova keypair-list[/mw_shl_code]


创建实例

列出flavors

感觉挺复杂的啊

我这样配置了，但是虚拟机还是无法上外网，是否还有其它配置？

命令创建实例后后 “Status” 是”error“,请各位给看下再排查下哪里。。。。？？？
过程如下：
1、创建实例
nova boot --flavor m1.tiny --image cirros-0.3.4-x86_64 --nic net-id=cdc7c1f0-09e5-4318-a0c3-4220b942c8f2 \
--security-group default --key-name demo-key demo-instance1
结果见附件1.png
2、检查实例
nova list
结果见附件2.png
3、查看nova-conductor.log有错误

tail nova-conductor.log

  File "/usr/lib/python2.7/dist-packages/nova/scheduler/manager.py", line 86, in select_destinations
    filter_properties)

  File "/usr/lib/python2.7/dist-packages/nova/scheduler/filter_scheduler.py", line 80, in select_destinations
    raise exception.NoValidHost(reason=reason)

NoValidHost: No valid host was found. There are not enough hosts available.

过程如下：
1、创建 ...

你的net_id是ext-net的还是demo-net的~同时在创建的时候也要看你是source的是admin-openrc.sh还是demo-openrc.sh文件。

你好，创建实例时，我用demo-net能够创建成功，但如果使用ext-net就会错误。是什么原因呢？

你好，创建实例时出现ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500)  怎么回事

谢谢啊 你这样的配置可以安装all in one么?

创建实例出现这个问题该怎么解决啊版主大大。
