On December 22nd just in time for Christmas SUSE has released the latest updated to their flag ship server distribution.
kernel level for 12.1 is kernel-3.12.49-11.1. As one of the top features this distribution is the first one, which allows full exploitation of the z13. And this distribution is so far the only one that’s supported by IBM’s version of KVM as well as Docker. SUSE has published a nice summary of the the z specific news.
And of course it has many bug fixes. So after the installation be sure to run an update to install the latest fixes from the maintweb.
Here is my usual summary of links to more information:

A frequently asked question is about the location of the older libstdc++ libraries that are needed for compatibility with older software products. There are two locations:
- the oldest ones are in a package called compat, that you can install with zypper directly. It has libstdc++-3-libc6.2-2-2.10.0.so and libstdc++-libc6.2-2.so.3
- the libstdc++33 is part of the Legacy Module that SUSE provides. Add it to your repositories with yast2 repositories and then you can install. It contains the libstc++.so.5
