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

  • vzkernel-firmware seems to be conflicting with kernel-firmware. Did you try to remove the default kernel package and leave only vzkernel?

  • Not tried removing anything yet. What would you suggest I should do / command.

  • To remove the default kernel package run command: yum remove kernel. Check the output of this command to make it's not going to remove any packages which you need.

  • When running that command to remove- I get Loaded plugins: fastestmirror Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package kernel.x86_64 0:2.6.32-431.17.1.el6 will be erased --> Finished Dependency Resolution

  • It doesn't list kernel-firmware as a dependency, so try to specify that separately: yum remove kernel kernel-firmware.

In your system vzkernel-firmware is conflicting with kernel-firmware. Because vzkernel packages are coming from outside the standard package repositories such conflict is not unusual.

The easiest way to solve this issue assuming that you don't use original CentOS kernel is to remove it. To do that run:

yum remove kernel kernel-firmware

Before proceeding check that it's not going to remove any packages which you need.

The accepted answer is incorrect, based on the official answer:

https://wiki.openvz.org/Vzkernel-firmware

Correct Answer:

You need to remove the vzkernel-firmware by running the following:

rpm -e vzkernel-firmware

And then adding the following to /etc/yum.repos.d/openvz.repo :

exclude=vzkernel-firmware

  • Theoretically it's safer to use both packages from the same repository. In cases when one or another repository updates their packages there is a possibility that versions will get out of sync.

  • Not on the RHEL 6 version. vzkernel-firmware is just given as a supplement for older versions.

We expected this problem many times when upgrading OpenVZ. IMHO best solution for this issue is: yum remove kernel. It's pretty safe and solve this issue forever. I have no ideas why you need standard kernel on OpenVZ nodes.

But please be careful and check many times about "What packages should remove yum" when removing kernel package.

  • Strange how the standard kernel was still installed, running 'yum remove kernel' has resolved the issue - Thanks
