LXC Error after launching the conatiner

Hi Guys,

I have a container created in my ubuntu 14.04 that is running on oracle virtual box.

once i start my container with below command i am getting the below error.

lxc-start --name cn-01

init: setvtrgb main process (421) terminated with status 1
init: plymouth-upstart-bridge respawning too,fast

After the above error there is no login prompt is visible.

As a fix i need to hit 'Enter' key after that i get a prompt for Login.

Is this a bug or Is there anything that i am missing during my installation?

Thanks
Sandeep
