this is a page for newer ubuntus (8 and 9)
This tutorial will teach how to install the newest Ubuntu versions through chroot (no templates required).
==Initial steps==
* Choose a number for your machine (example: 101)
* Choose an ubuntu version (this howto was tested with hardy, intrepid and jaunty)
* Go to the directory where the images will be placed:
cd /vz/private/
* Create a directory for the new machine:
mkdir 101
* Run debootstrap:
debootstrap --arch=i386 jaunty 101/ http://br.archive.ubuntu.com/ubuntu
(you can change the mirror if you want)
* Edit the machine configuration in /etc/vz/conf/101.conf. Configure its name, IP, memory and everything else
* Start the machine
vzctl start 101
==Fixing bugs==
===udev===
If you try to enter the machine you'll see an error:
eva:/vz/private# vzctl enter 101
enter into VE 101 failed
Unable to open pty: No such file or directory
To solve this, you'll have to remove udev from the boot:
eva:/vz/private# vzctl exec 101 'update-rc.d -f udev remove'
Removing any system startup links for /etc/init.d/udev ...
/etc/rcS.d/S10udev
Then you'll be able to enter the machine after restarting it:
vzctl restart 101
vzctl enter 101
Note: when you update the udev package you'll probably have to run the "update-rc.d -f udev remove" command again.
===klogd===
Type this command:
ps aux
You'll see that "init" didn't finish because the "klogd" process is still being run. You'll have to fix this:
update-rc.d -f klogd remove
Restart the machine and see the results:
exit
vzctl restart 101
vzctl enter 101
ps aux
===network===
For newer ubuntu versions, you'll notice that the network is not working. To fix this problem, you'll have to edit the /etc/init.d/networking script. You'll have to make it create the "/var/run/network" directory just after its "start":
case "$1" in
start)
mkdir -p /var/run/network # -> this is the new line
process_options
Then, start the networking:
/etc/init.d/networking start
(important: use start, not restart)
===gettty===
If you look at the running processes, you'll see that there are a lot of "/sbin/getty" processes. You can also remove these.
===Other init stuff===
Feel free to use 'update-rc.d' to remove any other unneded stuff =)
==Finish==
Now you're free to use your machine =)
You'll still probably want to add the "security" and "updates" repositories, install openssh-server, change the root password, update the system, change locales and other stuff. Enjoy =)
