Thanks for the quick reply, I'll stay with the old version for now. The host server will move to CentOS 6 in the not too distant future anyway, it's just not something I can do right away.

Regards,
Holger

Hi,

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?

There are two problems here:

1 ploop

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.

2 libcgroup

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.

In the meantime,
- please stay with vzctl-3.3 and
- maybe it's a good time for switching to RHEL6 kernel which has a lot of nice features such as VSwap.



Best regards,
Holger

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
