为什么lxc在lxcwebpanel中的功能与预期一样，而不是在CLI或python中？

Question

观察结果：

1. lxc-webpanel函数如预期
2. 从命令行界面发出的lxc命令，返回非零退出状态1
3. 从python解释器中的lxclite模块调用的函数会引发异常

问题：

我如何找到使lxc webpanel按预期运行的缺失因素？当我在bashshell中发出lxc命令时，或者当我从python解释器调用lxc webpanel相同的def时，lxc命令失败。在

目标：

能够使用bashcli或python会话来管理lxc容器

系统信息：

使用lxc webpanel创建了一个名为“test container”的容器。在

观察1:lxc webpanel试用截图

• The container 'test-container' exists.
• The container starts.
• The container stops.

观察2:bash CLI中的lxc命令

• 在：lxc-info -qn test-container

  输出：

test-container doesn't exist

• {cd3}

  输出：

attach.c: lxc_attach: 635 failed to get the init pid

观察结果3:lxclite def call from ipython3

• 在： import lxclite as lxc container = 'test-container' lxc.info(container)

ContainerDoesntExists Traceback (most recent call last) in () ----> 1 lxc.info(container)

../../python3_dev/_lxc/lxclite/init.py in info(container) 122 if not exists(container): 123 raise ContainerDoesntExists( --> 124 'Container {} does not exist!'.format(container)) 125 126 output = _run('lxc-info -qn {}|grep -i "State\|PID"'.format(container),

ContainerDoesntExists: Container test-container does not exist!

注意：lxc-checkconfig输出：

这条评论❝The user id in the lxc instance should equal the user id in the host.❞让我找到了我的解决方案。在

当我以root用户身份运行IPython会话时，一切都按预期运行。哼！在
