Introduction

Beginning with Proxmox VE 2.2, we introduced a new console view (with login capability). Especially for beginners it is not that easy to understand and manage containers but with the new console this is big step forward. OpenVZ and KVM console looks now quite similar.

But as most OpenVZ templates have disabled terminals, you need to enable it first. This article describes for the needed changes for already running OpenVZ container.

Note:

All Debian templates created with latest Debian Appliance Builder got this changes already, just download them vie GUI to your Proxmox VE storage (Debian 6 and 7 templates are up2date, 32 and 64 bit)

Debian

  • this will work for all Debian releases:

log in to the Proxmox host.

 vi /var/lib/vz/root/*/etc/inittab

 # add this
 :2345:respawn:/sbin/getty 38400 tty1


Debian Lenny 5.0

Login via SSH (or use the VNC "Shell") to your Proxmox VE host and 'vzctl enter CTID' the container:

List all running container:

proxmox-ve:~# vzlist
     CTID      NPROC STATUS    IP_ADDR         HOSTNAME
      108         23 running   192.168.9.20    ubuntu-1204.proxmox.com
      109         18 running   192.168.9.21    centos63-64.proxmox.com
      111         15 running   192.168.9.23    centos5-64.proxmox.com
      114         14 running   192.168.9.30    deb6-32.proxmox.com
      115         15 running   192.168.9.31    deb7-32.proxmox.com
      122         14 running   192.168.9.36    deb5.proxmox.com

Enter the container:

proxmox-ve:~# vzctl enter 122
root@debian:/# nano /etc/inittab

On the bottom of /etc/inittab just add the following line:

1:2345:respawn:/sbin/getty 38400 tty1

Save the changes and shutdown/start the container via Console.

Same as Debian Lenny 5.0

Debian Wheezy 7.0

Same as Debian Lenny 5.0

Ubuntu

Ubuntu 12.04

Login via SSH (or use the VNC "Shell") to your Proxmox VE host and 'vzctl enter CTID' the container:

List all running container:

proxmox-ve:~# vzlist
     CTID      NPROC STATUS    IP_ADDR         HOSTNAME
      108         23 running   192.168.9.20    ubuntu-1204.proxmox.com

      122         14 running   192.168.9.36    deb5.proxmox.com

Enter the container:

proxmox-ve:~# vzctl enter 108
root@ubuntu-1204:/# nano /etc/init/tty1.conf

Change/Create the file that it looks exactly like this:

# tty1 - getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]

stop on runlevel [!2345]

respawn
exec /sbin/getty -8 38400 tty1

Save the changes and shutdown/start the container via Console.

stop on runlevel [!2345]

respawn
exec /sbin/agetty -8 tty1 38400

Save the changes and shutdown/start the container via Console.

Troubleshooting

If you still want to use the previous method (vzctl enter CTID) you can open the host "Shell" and just type 'vzctl enter CTID" to manage your containers.

Java browser plugin

The console is using a Java applet, therefore you need latest Oracle (Sun) Java browser plugin installed and enabled in your browser (Google Chrome and Firefox preferred). If you are on Windows desktop, just go to java.com, if you run a Linux desktop you need to make sure that you run Oracle (Sun) Java plugin instead of the default openjdk. For Debian/Ubuntu based desktops, see Java_Console_(Ubuntu)
