As I've explained in this mailing list before, I create my own custom
CentOS template that has some history, being initially used as a
template for KVM based virtual machines, then OpenVZ based containers,
then libvirt-lxc containers, and now finally we're tackling LXC. One
issue I've noted is that when I create a container using my custom
template lxc-console does not work. When I connect I get something like
this:
# lxc-console -n vm-00
Connected to tty 1
Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself
and then at this point it basically hangs, just consuming whatever I
type but not attaching to the console and giving me feedback. If I use
same config file for the container but use the CentOS download template
instead, the console works as expected.
In comparing the two cases, I've noticed that when I'm running with the
downloaded template, I get a set of five getty processes:
# ps aux|grep agetty
root 37 0.0 0.0 6452 800 pts/0 Ss+ 22:45 0:00
/sbin/agetty --noclear --keep-baud pts/0 115200 38400 9600 vt220
root 38 0.0 0.0 6452 796 pts/1 Ss+ 22:45 0:00
/sbin/agetty --noclear --keep-baud pts/1 115200 38400 9600 vt220
root 40 0.0 0.0 6452 804 pts/2 Ss+ 22:45 0:00
/sbin/agetty --noclear --keep-baud pts/2 115200 38400 9600 vt220
root 41 0.0 0.0 6452 808 pts/3 Ss+ 22:45 0:00
/sbin/agetty --noclear --keep-baud pts/3 115200 38400 9600 vt220
root 42 0.0 0.0 6452 796 lxc/console Ss+ 22:45 0:00
/sbin/agetty --noclear --keep-baud console 115200 38400 9600 vt220
Using my own template, I only get a single console process:
# ps aux|grep agetty
root 279 0.0 0.0 6424 792 lxc/console Ss+ 13:57 0:00
/sbin/agetty --noclear --keep-baud console 115200 38400 9600
If I go ahead and start the processes manually, then lxc-console appears
to work as expected. My question, what am I missing in my template that
causes this behavior, or more specifically, results in the required
agetty processes failing to start when the container is started?
