Admins can now measure and view VM memory overcommit and utilization in a dashboard. They can use this information to determine whether their cluster is at risk due to memory overcommit or if it is underutilized. This helps them balance the workloads.

User story

As an VM Admin, I want to improve overall density. In our traditional VM environments, we find that we are memory bound much more than CPU. Even with properly sized VMs, we see a lot of memory just sitting around allocated to the VM, but not actually used. Moreover, we always see people requesting VMs that are sized way too big for their workloads. It is better customer service allow it to some degree and then recover the memory at the hypervisor level.
