This has been a long standing complaint of mine when people bring up Hyper-V…memory overcommit. I have heard the arguments against this and I’d really rather be the one choosing rather than lacking a feature I think really helps reduce the cost of virtualization and help the ROI impact that server (and soon desktop) virtualization can make. Now we’ll see when this gets rolled out, which is my other complaint of Hyper-V…tying a hypervisor to a OS release schedule.
