This article describes how you can update an existing precreated Debian or Ubuntu template. The procedure is pretty easy.

== Creating/configuring a temporary VE ==

First, you need to create a VE based on the template you want to update. Here is an example:

[HW]# vzctl create 555 --ostemplate debian-4.0-i386-minimal

Next, you want to specify an IP address and a nameserver:
[HW]# vzctl set 555 --ipadd x.x.x.x --nameserver y.y.y.y --save

You can get the value of nameserver from your /etc/resolv.conf. Your VE should have an Internet access, so you either supply a public IP, or see [[using NAT for VE with private IPs]] for information about how to use private IP and NAT.

Finally, check that Internet is working from inside a VE:
[HW]# vzctl exec 555 ping -n 3 www.ru

== Update ==

Enter the VE:
[HW]# vzctl enter 555

Update metadata and install updates:
[VE]# apt-get update && apt-get upgrade

Cleanup:
[VE]# apt-get clean
[VE]# > /etc/resolv.conf

Clean unused log files, .bash_history etc, then exit from a VE:
[VE] # exit

Stop a VE, remove its IP.

== Packing a new template cache ==

Now, rename the existing template cache:
[HW]# mv /vz/template/cache/debian-4.0-i386-minimal.tar.gz{,-old}

Now create a new tarball:
[HW]# cd /vz/private/555
[HW]# tar czf /vz/template/cache/debian-4.0-i386-minimal.tar.gz .

Clean up:
[HW]# vzctl destroy 555
[HW]# rm -f /etc/vz/conf/555.conf.destroyed

== Test new template cache ==

First, compare the sizes of the old and the new template caches:
[HW]# ls -lh /vz/template/cache/debian-4.0-i386-minimal*
-rw-r--r-- 1 root root 55M 2007-11-13 18:11 /vz/template/cache/debian-4.0-i386-minimal.tar.gz
-rw-r--r-- 1 root root 53M 2007-08-31 02:46 /vz/template/cache/debian-4.0-i386-minimal.tar.gz-old
The sizes should not differ much.

Try to create and start VE made from your new template:
[HW]# vzctl create 222 --ostemplate debian-4.0-i386-minimal
[HW]# vzctl set 222 --ipadd 10.0.0.222 --save
[HW]# vzctl start 222
[HW]# vzctl enter 222

Now execute a few basic commands to check VE is fine. Examples are: <code>ps axf</code>, <code>dpkg -l</code>, etc.

Finally, clean up the testing VE:
[HW]# vzctl stop 222
[HW]# vzctl destroy 222
[HW]# rm -f /etc/vz/conf/222.conf.destroyed
