Hello,
I have a Ubuntu Precise host, where I created a few test containers using
the following commands:
lxc-create -n env3 -t ubuntu -- -r precise
lxc-create -n env4 -t ubuntu -- -r natty
lxc-create -n env5 -t ubuntu -- -r maverick
lxc-create -n env6 -t ubuntu -- -r lucid
Every distribution besides Maverick works straight after installation with
no additional configuration! This is a welcome change compared to when I
first tried LXC a year or two ago, and nothing worked out of the box.
Running lxc-start with the Maverick container results in the whole process
becoming unresponsive:
root@HOST:~# lxc-start -n env5 -o env5log -l DEBUG
init: ureadahead main process (6) terminated with status 5
init: console-setup main process (24) terminated with status 1
init: procps main process (25) terminated with status 255
init: ureadahead-other main process (29) terminated with status 4
init: rsyslog main process (33) terminated with status 1
init: rsyslog main process ended, respawning
init: plymouth main process (8) killed by ABRT signal
init: plymouth-splash main process (47) terminated with status 2
I've included the logs below:

Any ideas? Is the final warning fatal?
