"KVM for IBM z Systems Version 1.1.2 will be the last release delivered by IBM. However, IBM will continue to provide the Linux and KVM enablement for z Systems [...]"Make no mistake: The withdrawal only affects the product KVM for IBM z. It does not mean the end for KVM on z (our open source effort to support KVM on IBM z Systems). To the contrary, development will not only continue unaffected, but the options for users grow, especially with the recent addition of SuSE to the existing support in Ubuntu.
