[PVE-User] Can't login to LXC containers

[Filippo Valsorda]

Hello, I am on the 4.0 beta.

I started a container, typed a password in the first screen, and chose
the Ubuntu 14.04 template.

Now I don't know how to login. If there is a default user name it's not
"ubuntu". If that password becomes the root password, then I have a
problem because I looked inside the template, and sshd_config has
"PermitRootLogin without-password".

I feel dumb asking such a simple question, but: how am I supposed to log
in to a LXC container?
