Editing Yum

'''Yum''' is nice package manager for RPM-based systems. If you are already using yum, you can set up OpenVZ yum repository and install/update OpenVZ software using yum.

== Setup ==

Download [http://download.openvz.org/openvz.repo openvz.repo] file and put it to <code>/etc/yum.repos.d/</code> directory on your server. You are all set.

== Usage ==

=== Upgrade ===
If you have OpenVZ already installed, just run
<pre>
# yum update
</pre>
periodically to keep your system up to date.

=== New installation ===
Run
<pre>
# yum install ovzkernel vzctl
</pre>
to install OpenVZ on your system.

{{Note|barely installing those packages is not enough to have OpenVZ up and running on your system. For full installation instructions, see [[Quick installation]].}}.

== Additional kernels ==
File <code>openvz.repo</code> by default enables only one repository — the one which contains latest stable kernel and tools. If you want to run some other OpenVZ kernel (e.g. development one, or a kernel made from some vendor's one), please edit <code>/etc/yum.repos.d/openvz.repo</code> manually, changing the line <code>enable=0</code> to <code>enable=1</code> for the kernel you want.

== Troubleshooting ==

=== Fedora Core 6: complain about newer kernel ===

On Fedora 6 system you can get the error while installing OpenVZ kernel using yum, like this one:

 Transaction Check Error:   package kernel-2.6.18-1.2869.fc6 (which is newer than kernel-2.6.18-ovz028test010.1) is already installed
  package kernel-2.6.19-1.2895.fc6 (which is newer than kernel-2.6.18-ovz028test010.1) is already installed

To work around this, disable kernel packages in fedora-core and fedora-updates repositories, by adding this line:

 exclude=kernel kernel-smp kernel-enterprise

to the
* [core] section of /etc/yum.repos.d/fedora-core.repo file
* [updates] section of /etc/yum.repos.d/fedora-updates.repo file
