Installing Oracle Linux 6.5 plus Unbreakable Enterprise Kernel (UEK) into a VMware Guest


The readme for media pack B75461-01, aka “Oracle Linux 6 Update 5 (6.5.0) Media Pack v1 for x86 64 bit”, see https://edelivery.oracle.com, states the following about getting the “Unbreakable Enterprise Kernel (UEK)” installed and running:

For compatibility reasons, the default installation image of Oracle Linux boots the Red Hat compatible kernel to perform the installation. Oracle provides an alternative installation image that supports the installation of Oracle Linux 6.5 using the Unbreakable Enterprise Kernel (UEK) as the installation kernel. This installation method also supports creating a root file system using the Btrfs file system.

Further on they recommend to download both the “Oracle Linux 6 update 5 DVD media” (pkg#1) and the “Oracle Linux 6 update 5 UEK boot ISO” (pkg#2), mounting and extracting pkg#2 to some tmp directory, mounting pkg#2, replacing the images directory of pkg#1 with the images directory of pkg#2 and finally providing pkg#1 on a path accessible via nfs or http.

Installing into a VMware guest may employ a shortcut, however, by configuring two cd/dvd drives before the installation and connecting “Oracle Linux Release 6 Update 5 UEK Boot ISO image for x86_64 (64 bit), Part Number V41364-01” as well as “Oracle Linux Release 6 Update 5 for x86_64 (64 Bit), Part Number V41362-01” locally (saving me from doing nfs / http as well), in that order. Do note, that the order is important, e.g. “IDE 0:0” followed by “IDE 1:0”, to have the UEK image actually booting up. Besides watching out for kernel name and version boot messages, one will eventually find out about the kernel on install when trying to configure a btrfs file system during installation, which is not available for the legacy (red hat) kernel.

This presentation was was very much appreciated https://www.youtube.com/watch?v=ioksH3xdxQQ, albeit featuring “Oracle Linux 6 update 4” and not refering to UEK at all, thanks to Ceyhun Kirmizitas.
