      Requirement description:

      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.

      MVP:

      • Move SWAP to beta (OCP TP)
      • Dashboard for monitoring
      • Make sure the scheduler sees the real memory available, rather than that allocated to the VMs.
