    Regarding your last paragraph about imbalanced clusters: it’s also somewhat amusing to see the constant vMotion of a single VM between two hosts in a three-host cluster to alleviate a workload when using DRS in it’s most aggressive mode.

    “…the ability to define cluster-level startup automation…”

    I have wanted this for so long. After any downtime of my home-lab, I would like to power on all my hosts and know that within half an hour all my critical and important VMs are auto powered on, in the correct order without me having to do anything.

    DRS is very conservative, it assumes that moving a VM is not a painless operation.
    But sometime, seeing an highly imbalanced cluster, even I set DRS to “Aggressive” and run without mercy!

    I was curious about the script. So using it as a start I modified to do the same with CPU, not sure it helped (CPU on the cluster I tried has very low usage).
