Thanks Mark. That is more or less what I thought. BTW I only just noticed that the IBM-speak in the SOD in the z13 announcement said 'IBM intends to **support** a Kernel-based Virtual Machine (KVM) offering for z Systems' (my highlighting). ie 'support' not 'deliver'. Keith

While qemu is _capable_ of emulating other architectures, that's not how we build it or ship it. The intent is not to provide an alternative to z/VM, however. The intent is to help new-to-the-mainframe customers get started with virtualization on the platform using a tool they probably already know pretty well. Lowering the barriers to entry in order to help convince them that mainframes really are a good idea. I envision people using KVM on System z eventually deciding they want to upgrade to z/VM for the better capabilities and manageability it provides. > Also does anyone have any guesses about IBMs Statement of Direction about > KVM that was in the z13 announcement.

My pure, unadulterated, WAG is that it will be z13 (or later) only, a priced IBM product, and that it will not emulate Intel. That just feels how IBM would approach things given their history.
