Tags: Proceedings , SHARE in Anaheim 2012 , 2012

2012 marks the 45th anniversary of the announcement of the System/360 model 67 and the CP/67 hypervisor and the 40th anniversary of the announcement of System/370 virtual storage and the VM/370 hypervisor. Jim Elliott has spent most of his 39 years at IBM working on the various iterations of VM from CP/67 and VM/370 through to today's z/VM. Join Jim for a personal review of the ups and downs in the evolution of "real VM" over the last 45 years which have brought us to today where z/VM is essential to running Linux on System z and where virtualization is in common use on most server architectures.
