While updating vzctl to latest on CentOS-5.8, I was getting the below error:

# yum update vzctl

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
    &nbsp;    &nbsp;    &nbsp;    &nbsp;    package-cleanup --dupes
    &nbsp;    &nbsp;    &nbsp;    &nbsp;    rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

Turns out that ploop is no longer required for vzctl on CentOS-5.8 and can be removed:

yum update problem on CentOS 5.8 server

"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."

The solution was to remove ploop in single transaction as mentioned:

# yum shell
> update vzctl
> remove ploop\*
> run
> quit
