yum install vzkernel [message #44094]

When I run "yum install vzkernel" yum offers to delete the second-oldest version. Very practical, but I'd like to keep a few older versions than just one. How do I do that? I don't see anything in openvz.repo that would do that.

Yeah thanks. I obviously tried that already. Can you be a little more specific. What am I looking for?

try to use yum update when you want to save your previous kernel.
yum install kernel, will always delete oldest one.

Thanks, but that makes no difference:

The first thing to do when searching for general answers like this is to open Google (or whatever you use), enter 'keep more than 3 kernels' and follow some of the top hits.

But really, using yum update, install or whatever, won't make any difference without additional settings so it's probably time to put the correct answer here - what you're looking for is 'installonly_limit' in "/etc/yum.conf".

Thank you, finally a straight answer.

Turns out installonly_limit is already set in yum.conf to 3, but not active until installonlypkgs is set to vzkernel*.

PS. What makes you think I didn't try Google? I didn't find the answer which is why I asked here.

That's odd, I get 3 of both kernel and vzkernel packages, without any additional settings. The oldest one gets uninstalled when a new one appears, unless it's active at the moment.

I'm assuming that changing installonly_limit to 5 would get me a 5 of each, kernel and vzkernel but I didn't do that for a long time.

BTW, a setting in "/etc/sysconfig/kernel" should tell yum to always keep vzkernel as default in grub.conf. I still check before every restart (old habits...), but it's handy.

I'd like to warn anyone not to try this.

I added following to /etc/yum.conf:

installonlypkgs=vzkernel*
installonly_limit=5
exclude=kernel*

Then ran yum update:

I had to manually force-install the previous kernel rpms to at least have one backup in case of a problem after rebooting.
