<p class="MsoNormal"><span lang="EN-US">I tried to run yum
update on a CentOS 5.8 OpenVZ host server today and
something strange happened. Yum tries to update vzctl-core
to version 4.0-1, which seems to require an updated plop-lib
package, but the updated plop-lib package from the yum
repository requires a kernel >= 2.6.32 (CentOS 5 runs on
2.6.18). As a result, the entire update fails. It looks like
there are the wrong package versions in the yum repository
for RHEL/CentOS 5 – or is there something else going on?</span></p>

<br>
There are two problems here:<br>
<br>
1 ploop<br>
<br>
Since you have RHEL5-based kernel that do not require ploop, you can
remove ploop when installing vzctl-4.0. I have made vzctl not
requiring ploop by dynamically loading it when it's available. Note
that vzctl is not requiring ploop anymore, it just conflicts with
the old version of it.<br>
<br>
2 libcgroup<br>
<br>
Currently I don't have a solution rather than compiling libcgroup
from source. I will take a closer look in the coming days and find a
fix.<br>
<br>
In the meantime, <br>
- please stay with vzctl-3.3 and <br>
- maybe it's a good time for switching to RHEL6 kernel which has a
lot of nice features such as VSwap.<br>
