z/VM 6.3

After a long waiting time IBM released the latest version of z/VM. Now there is way more information available than just the little bit I described in my preview

The major items haven’t changed from the preview – it’s CPU scalability using Hiperdispatch and support for 1 TB per z/VM instance.

The announcement also has a statement of direction for z/VM 5.4.  Basically it says that the current System z generation (EC12 /BC12) will be the last one that’s supported with z/VM 5.4. And support for z/VM 5.4 will end whenever the z9 hardware support ends. So it’s time to plan for the upgrade to z/VM 6.3.
