Having a lot of experience with WLM on z/OS this is a must moving forward and I expressed that to IBM. Actually it even goes further than just z/VM at some point being able to control the priorities of the individual z/Linux processes would be great.
Going further, a real workload manager MUST deal at the guest, the hypervisor, the LPAR and the box level. IBM cannot omit the LPAR and hypervisor layers, eg z/VM.
