Note: This procedure assumes you are using xCAT 2.6.1 or later.
The kerneldir attribute in linuximage table can be used to assign a directory containing kernel RPMs that can be installed into diskless images. The default for kernerdir is /install/kernels. To add a new kernel, create a directory named <kernelver> under the kerneldir, and genimage will pick them up from there.
To add a new kernel, create a directory named <kernelver> under ``/install/kernels`` directory, and ``genimage`` will pick them up from there.
The following examples assume you have the kernel RPM in /tmp and is using the default value for kerneldir (/install/kernels).
The following examples assume you have the kernel RPM in ``/tmp`` and is using a new kernel in the directory ``/install/kernels/<kernelver>``.
The RPM names below are only examples, substitute your specific level and architecture.
