zEC12 and zBC12 the last System z servers to support z/VM 5.4

This might be an interesting bit of information I came across today for customers still using z/VM 5.4. In the announcement of z/VM 6.3 there was also this statement of direction :

"Stabilization of VM z/V5.4 support
The IBM zEnterprise EC12 and IBM zEnterprise BC12 are planned to be the last System z servers supported by z/VM V5.4 and the last System z servers that will support z/VM V5.4 running as a guest (second level). z/VM V5.4 will continue to be supported until December 31, 2014, or until the IBM System z9® EC and IBM System z9 BC are withdrawn from support, whichever is later. Refer to Withdrawal Announcement ZP12-0335, dated August 07, 2012".

So, just keep it in mind : z/VM 5.4 will no longer be supported on the next generations of System z in any form.

By the way, 'stabilization' is a typical IBM word with a specific content. It always gets my immediate attention because it really means : we immediately stop all further effort for this product and from now on it's a dead end street.
