I’ve one more problem before proceeding with the rollout of our new 5.12 setup.
In previous versions, I managed to overcommit memory and CPU to the max - I don’t really care in all honesty. We never ran out of resource as CPU was mostly idling and I could deploy as many VM’s as needed without impacting the system. In the new version, I want to to the same thing. The ESX cluster has 830GB real RAM, which I’ve successfully over provisioned to 1.6TB, but CPU overcommitment is a mess.
Right now, reserved CPU and RAM are both 0% (I’ve tried dropping CPU to -100%), but the allocated CPU is showing 1800/6000 with about 6 VM’s running but the real CPU is showing @ 2510%, and nothing I do in the overcommitment CPU slider (or entering any value) makes any difference. The physical cluster has 120 cores, but I just need to get the CPU overcommit as high as possible. In a previous version (5.6) the real CPU overcommit was running at 86400. The other thing I noticed is that the none of the ESX hosts show any Real Memory for some reason.
