Now zVM is adding vmotion from VMware, so they call it Single System

Actually, no. "Single System Image" is a cluster architecture. "Live
Guest Relocation" (which requires an SSI cluster) is just one of the
services that an SSI cluster will provide. [See my other post.]

So SSI (zVM0 is HA (VMware) and Live Guest Relocation (zVM) is vmotion
(VMware).
The architecture is SSI or HA and LGR or vmotion is what you can do with
the architecture.
