=Etch (testing)=
OpenVZ is now a part of Debian Etch (a.k.a. "testing") repository. This article describes how to install OpenVZ on a Debian Etch system.
To install the kernel-source, OpenVZ kernel patch and utilities, run the following:
aptList of precompiled kernel-images linux-image-2.6.18-openvz-486_02_i386.deb linux-image-2.6.18-openvz-686_02_i386.deb linux-image-2.6.18-openvz-amd64_01_amd64.deb linux-image-get update2.6.18-openvz-ia64_01_ia64.debapt linux-image-2.6.18-get install kernelopenvz-package k7_02_i386.deb linux-sourceimage-2.6.18 kernel-patchopenvz-sparc64-smp_01_sparc.deb linux-image-2.6.18-openvz vzctl vzquota-sparc64_01_sparc.deb
== Creating the kernel package ==Example: Installing an OpenVZ precompiled Debian Kernel-Image for an i686:
First you need to unpack the <pre> # wget http://download.openvz.org/kernel:/debian/etch/linux-image-2.6.18-openvz-686_02_i386.deb # dpkg -i linux-image-2.6.18-openvz-686_02_i386.deb</pre>
cd /usr/srctar xjf # apt-get install kernel-package linux-source-2.6.18.tar.bz2cd linuxkernel-patch-sourceopenvz libncurses5-2.6.18dev
Next, you need to get a kernel config. You can use the config of the debian-kernel:
cp # cd /bootusr/configsrc # tar xjf linux-source-2.6.18.tar.bz2 # cd linux-3source-686 2.config6.18
Now you can apply openvz kernel patch and compile the kernel:
make # cp /boot/config-kpkg 2.6.18-3-append_to_version=-1-openvz --added_patches=openvz --revision=1 kernel_image --initrd686 .config
You will have to answer some config-questions. Usually, the provided defaults will suffice.

add info's about precreated debian at download.openvz.org, add minor hints

== installing the kernel-images, toolset and debian-os-template ==Example: install the stable OpenVZ kernel, tools and debian Debian OS Template
# aptitude install ovzkernel-2.6.9 vzctl vzquota vzctl-ostmpl-debian
Maybe you need to update you "linux-loader" (can be configured at /etc/kernel-img.conf) for the "GRUB": # /sbin/grub-update
Reboot in your new Debian Stable OpenVZ System
# reboot
That's all :-)
Now it's time to setup your VE's with the minimal Debian-3.1 Template, create new one or download another precreated OS-Template.
=Etch (Testing) = Installing OpenVZ is now a part of Debian Etch (a.k.a. "testing") repository. == install the utilities and kernel patch -image == === use precomiled kernel images ===Can be found at http://download.openvz.org/kernel/debian/etch/
<pre>
</pre>
=== or build your own kernel-image (debian way) ===
To install the kernel-source and the OpenVZ kernel patch, run:
<pre>
</pre>
Unpack the kernel-source:
<pre>
</pre>
You need a kernel config.
You can use the config of the debian-kernel:
<pre>
</pre>
Or get a 2.6.18 kernel config from http://download.openvz.org/kernel/devel/current/configs/ <pre> # wget http://download.openvz.org/kernel/devel/current/configs/kernel-2.6.18-028test007-i686.config.ovz -O .config</pre> Now you can apply openvz kernel patch and modify your kernel-config:<pre> # ../kernel-patches/all/apply/openvz # make menuconfig</pre> You need following OpenVZ kernel config settings:<pre></pre> Compile your Kernel (as user root, or you need the --fakerootcmd!)<pre> # make-kpkg --append_to_version=-1-openvz --added_patches= Install the kernel package =openvz --revision=1 kernel_image --initrd</pre>
Install the kernel and update initramfs:
<pre>
# dpkg -i ../linux-image-2.6.18-1-openvz_1_i386.deb
# update-initramfs -c -k 2.6.18-1-openvz
</pre>
INFO: update-initramfs is done, when make-kpkg is use with --initrd option
INFO: update-grub can be configured by /etc/kernel-img.conf
Update the bootloader (when not done above)
GRUB :
# /usr/sbin/update-grub
INFO: since the Debian ETCH-release the location of update-grub is moved from /sbin/update-grub to /usr/sbin/update-grub !
== install the toolset ==
You need the toolset for manage-ing OpenVZ Virtual Enviromennt (VE)
<pre>
# apt-get install vzctl vzquota
</pre>
== modify needed settings ==
Debian Way:
If you want network access for the virtual server then you need to enable IP forwarding. Set "ip_forward" to yes in /etc/network/option.
# editor /etc/network/options
In some cases you may need to enable proxy_arp for the network devices that you want your virtual hosts to be accessible on.
You can add this to a specific interface in the network configuration (/etc/network/interfaces) by the following lines, replace %DEV% with your device name (ie. eth0).
