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'.

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.

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.
