Guide how to change kernel version of linux for OCSM.
Default kernel depends on the version the system was installed with as it does not change across upgrades. The available kernels depend on the version the system was installed with but as well on the current version:
pre-188.8.131.52.0 versions (not current, but the version the server was installed with)
OCSM comes with the 2.6 and 3.2 Linux kernels, but boots the 2.6 kernel by default. If the system was upgraded from older version to the 184.108.40.206.0 and higher, kernel 3.16 has been added but the default kernel remained as noted. Thus such system would have 3 kernels: 2.6, 3.2 and 3.16.
Scope - use cases for changing a kernel:
1. When OCSM is being installed on a virtualization solution that is based on the Xen hypervisor (e.g. Oracle VM), this default behavior needs to be changed, in order to have the xen-blkfront driver available (which provides support for Xen virtual block devices).
2. Newer server models might require newer drivers that add support for their components.
