CentOS

Where can I find an archive of kernels and how do I install a specific one. In my case I need to install kernel 4.9 in an attempt to reproduce a customer issue.

We don't ship a 4.9 kernel. CentOS 7 uses 3.10 and CentOS 6 uses 2.6.32.

If the customer has CentOS 7 and kernel 4.9, then where did they got that?

If the customer has something else than CentOS 7, can you mimic that environment in Docker container?
Furthermore, if the kernel is not the only difference to CentOS 7, is kernel still the culprit?


ElRepo does pack some kernels: http://elrepo.org/tiki/kernel-ml and http://elrepo.org/tiki/kernel-lt
Alas, they don't include 4.9, but ElRepo archives do http://elrepoproject.blogspot.fi/2012/0 ... hives.html

Thanks, the archives link is exactly what I am looking for. I am kind of assuming that they updated their kernel to kernel.ml (I am guessing that ml stands for main line?) when kernel.ml was at version 4.9. I'm speculating here a bit, but based on the versions (4.4) it seems that kernel.lt is the last stable, I'm curious if I'm right about "ml", and what "lt" stands for.

Get them run rpm -q kernel so we can see the package name. ELRepo do a 4.9 kernel and the package name will have '.elrepo' in it if so. It might also be a kernel from the xen SIG which also do a 4.9 kernel.

As for ml and lt: mainline and long term (aka LTS) - both are kernels from kernel.org.
