[Lxc-users] lxc doesn't work on Fedora 13

I have lxc working pretty well on my Ubuntu Lucid box.  Now I'm trying
to get it to work on my Fedora 13 laptop but I can't seem to get it to
connect to any guest consoles.

Here's an example:

     [root at lyra-f13 ubu-guest]# lxc-start -f config -n ubu-guest -o
$(tty) -l DEBUG
      lxc-start 1284711204.849 DEBUG    lxc_conf - allocated pty
'/dev/pts/8' (4/5)
...
      lxc-start 1284711204.884 NOTICE   lxc_start - exec'ing '/sbin/init'
      lxc-start 1284711204.886 NOTICE   lxc_start - '/sbin/init'
started with pid '14166'
      lxc-start 1284711204.886 DEBUG    lxc_utmp - Added
'rootfs/var/run' to inotifywatch

Things look OK but when I try to connect from another terminal:

    [root at lyra-f13 bronson]# lxc-console -n ubu-guest
    Type <Ctrl+a q> to exit the console

Nothing happens.  It just hangs until I exit the console (well,
characters are echoed back).

This appears on the debug console when I try to connect.

      lxc-start 1284711279.657 DEBUG    lxc_commands - peer has disconnected


I rsynced this guest to my Ubuntu Lucid box and everything works
great.  lxc-start fires right up, and lxc-console connects and
immediately prompts for a login.

Any idea why lxc isn't working in F13?  This happens for all guests
that I try -- Ubuntu, Debian, and Busybox, all of which work on Lucid.
 I'm using stock distro kernels.  Thanks!
