[Lxc-users] problem starting a container

[Daniel Stefaniuk]

Hi all

A command to start a container gives me following output:

    init: ureadahead main process (6) terminated with status 5

Then the container seems to bu up and running. However, if I try to login
to that
container using lxc-console I get only this message "Type <Ctrl+a q> to
exit the console".
Any clues as to why this happens?

container's syslog:
