Seeing some strange behavior running fedora 12 for both host and lxc container.
I do a define, start and console :

[root at fedora12new lxc-libvirt-scripts]# virsh -c lxc:// console testf12new
Connected to domain testf12new
Escape character is ^]
--> I press enter here and virsh exits.

I don't get login prompt always. Sometimes I do and when I try to
login it rejects my password. Apparently, the same rootfs works fine
with lxc tools and I can login.

Snippet from  etc/event.d/tty1 :
respawn
exec /sbin/mingetty pts/0

I use "exec /sbin/mingetty tty1" for lxc tools and that works fine. I
had to try pts/0 for libvirt since tty1 does not even get me the
occasional login prompts I get with pts.

Also even after virsh shutdown, I see that the container processes do
not exit. Is there something else I should do?
