[Lxc-users] Alternative to Debian Testing? No Prompt upon lxc-console execution

These may be idiotically simple suggestions, but I've been caught in these

Sometimes when I use lxc-console, I don't see anything until I press
"enter". Try this first.

Also, what happens if you start  the container without the -d option? Does
it bring you into a console then? lxc-console won't work, if lxc-start
(sans daemon option) doesn't bring you to a prompt (at least in my
experience with LXC in Squeeze).
