How to review the Kernels available from the ELRepo repository

Question

How do I list the available kernels in the ELRepo repository?

Answer

You can use the following command to list available packages from only the repository elrepo-kernel.

yum list available --disablerepo='*' --enablerepo=elrepo-kernel

The system should return a list of available kernels. Lines that include kernel-lt  signify a stable, long-term support release. While lines with kernel-ml indicate a mainline release with a shorter support term, but with more frequent updates. In the right-hand column, there is a series of letters and numbers that represent the kernel version. This will look something like '4.4.113-1.e17.elrepo'. You can use these two pieces of information to decide which kernel version and release you want to install.
