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
