Creating a LXC virtual machine template (from scratch)

I have chosen to put all virtual machines in a /mnt/vm folder, for which I've created a separate partition. Here I will put the virtual machine files, configs and scripts.

Making a template out of your container saves you a lot of time when you need to add an extra container.

creating a lxc container template from scratch (using debootstrap) Install debootstrap:

apt-get install debootstrap

Download the 'squeeze' debian distribution files into a tarball archive:

vm-mgr:/mnt/vm# debootstrap --make-tarball=debootstrap-squeeze-tarball.tar squeeze <BEGIN GeSHi>/mnt/vm/vm-template<END GeSHi>

It will create a .tar file of about 60MB. Install a base system using the just created tarball archive. I've selected the 'minimal base' debian installation variety, as I want to keep the size of the debian container small. I opted to extract the files to /mnt/vm/vm-template.:

debootstrap --variant=minbase --unpack-tarball=debootstrap-squeeze-tarball.tar squeeze <BEGIN GeSHi>/mnt/vm/vm-template<END GeSHi>

Add a network bridge (make sure bridge-utils is installed on the vm-mgr): In /etc/network/interfaces, comment 'allow-hotplug eth0' out, then add:

auto br0
iface br0 inet static
        address <BEGIN GeSHi>192.168.0.2<END GeSHi>
        netmask <BEGIN GeSHi>255.255.255.0<END GeSHi>
        gateway <BEGIN GeSHi>192.168.0.1<END GeSHi>
        bridge_ports <BEGIN GeSHi>eth0<END GeSHi>
        bridge_fd 0

Create the bridge by hand by entering:

brctl addbr br0 eth0
#brctl addif br0 eth1

Configuration files and scripts

nano vm-template.fstab

nano vm-template.start.sh
lxc-stop -n <BEGIN GeSHi>vm-template<END GeSHi>
lxc-destroy -n <BEGIN GeSHi>vm-template<END GeSHi>
lxc-create -n <BEGIN GeSHi>vm-template<END GeSHi> -f <BEGIN GeSHi>/mnt/vm/vm-template.config<END GeSHi>
sleep 2
lxc-start -n <BEGIN GeSHi>vm-template<END GeSHi> -d
sleep 2
lxc-console -n <BEGIN GeSHi>vm-template<END GeSHi>
chmod ugo+x vm-template.start.sh

I haven't checked the neccessity of 'sleep 2' yet.

Fixing things

Running Debian from a lxc container requires some small adjustments to make things work.

Before fixing these things, we will have to make debian think it is running from the vm-template directory we've just created. We can do this with the change-root command ('chroot'):

cd <BEGIN GeSHi>/mnt/vm/vm-template<END GeSHi>
root@vm-mgr:/mnt/vm/vm-template# chroot .
root@vm-mgr:/#

Change the root password

This is a basic but very important step to do, as you don't want your container to have a default password.

root@vm-mgr:/# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@vm-mgr:/#

Disable some TTY's

Disabling tty's is required to make lxc containers work.

nano /etc/inittab

Change:

5:23:respawn:/sbin/getty 38400 tty5
6:23:respawn:/sbin/getty 38400 tty6

to

<BEGIN GeSHi>#<END GeSHi>5:23:respawn:/sbin/getty 38400 tty5
<BEGIN GeSHi>#<END GeSHi>6:23:respawn:/sbin/getty 38400 tty6

Create some devices:

cd /dev
mknod -m 666 tty1 c 4 1
mknod -m 666 tty2 c 4 2
mknod -m 666 tty3 c 4 3
mknod -m 666 tty4 c 4 4

Remove the time/clock files

Some of the init scripts try to initialize the hardware clock. We will prevent this by making these init-script non-executable:

chmod ugo-x /etc/init.d/hwclock*

Error:

startpar: service(s) returned failure: hwclockfirst.sh hwclock.sh ... failed!

Remove the files in rc#.d as well.. ? ? http://lxc.teegra.net/#_etc_inittab

Configuring network

nano /etc/network/interfaces

auto eth0
iface eth0 inet static
        address <BEGIN GeSHi>192.168.0.3<END GeSHi>
        netmask <BEGIN GeSHi>255.255.255.0<END GeSHi>

        dns-nameservers <BEGIN GeSHi>8.8.8.8<END GeSHi>

nano /etc/hostname

vm-template

Append vm-template to /etc/hosts file:

nano /etc/hosts
127.0.0.1       localhost <BEGIN GeSHi>vm-template<END GeSHi>

apt

Edit the apt sources list (where it downloads the software packages from)

nano /etc/apt/sources.list

change mirror to something local, see http://www.debian.org/mirror/list add security update server to the file:

deb http://security.debian.org/ squeeze/updates main contrib non-free

Update the list of packages:

apt-get update

Install apt-utils, which contain some basic tools for package maintenance:

apt-get install apt-utils

Correcting the hostname

Edit the hostname (make sure you are still in the chroot!):

echo "vm-template" > /etc/hostname
nano /etc/hosts

add:

127.0.0.1 localhost vm-template

Decreasing size of the vm-template

Clear /var/cache/apt/archives and do an 'autoremove' (removes orphaned packages(?)):

apt-get clean
apt-get autoremove

The '/usr/share/locale' folder takes a lot of space:

du -c -s /usr/share/locale/
  33548   locale/

So let's remove these locales (select correct locale when asked, I chose 'en_US UTF8(?)'):

apt-get install localepurge
localepurge
  localepurge: Disk space freed in /usr/share/locale: 32704 KiB
  localepurge: Disk space freed in /usr/share/man: 2376 KiB

Screen

screen - screen manager with VT100/ANSI terminal emulation

http://www.slac.stanford.edu/grp/cd/soft/epics/extensions/iocConsole/screen.1.html

apt-get install screen

When started, screen displays an introduction screen, to remove this,

nano /etc/screenrc

change:

#startup_message off

to:

startup_message off

You can use screen to start the containers, remember: ctrl-a a to send a ctrl-a to the 'inside' process. To end a 'lxc-start -n container_name' command (if you haven't used the '-d' option to daemonize it), open another shell and use 'lxc-stop -n container_name'

Regenerate SSH system keys

in the manager:

root@vm-mgr:~/# ssh-keygen
root@vm-mgr:~/# cat /root/.ssh/id_rsa.pub >> /vm-template/root/.ssh/authorized_keys
root@vm-net:~/.ssh# nano -w authorized_keys
na het kopieëren van een template naar een nieuwe vm, ssh-keygen draaien:
vm-template# 
echo y | /usr/bin/ssh-keygen -t rsa -N "" -f /etc/ssh/ssh_host_rsa_key
echo y | /usr/bin/ssh-keygen -t dsa -N "" -f /etc/ssh/ssh_host_dsa_key
'echo y'  because it may ask to overwrite the ssh_host_dsa/rsa_key file if it already exists.
?-C comment ?  -t rsa1?

after copy template to new folder, EDIT CONFIG!
