我在fedora-20中使用默认配置文件和默认的fedora模板创建了一个lxc容器。
lxc-create -n root -t fedora
当我尝试启动容器时，我会收到用户名和密码提示。
在ubuntu中，似乎他们使用默认的“ubuntu”作为用户名和密码。我尝试使用模板中指定的“root”之类的密码的不同组合，但无法登录。
这是输出：
[root@localhost ~]# lxc-start -n root
systemd 208 running in system mode. (+PAM +LIBWRAP +AUDIT +SELINUX +IMA +SYSVINIT +LIBCRYPTSETUP +GCRYPT +ACL +XZ)
Detected virtualization 'lxc'.

对我来说lxc-attach -n root有效。它chroots到系统，你可以从那里设置root密码。
