On any given host, what is the maximum CPU and Mem than can be reserved for the VMs running on that host when totaled up?
What is reserved by the host for itself, and unavailable for reservations? Does this vary at all?
The max amount varies based on the host and its resources along with kernel services being used. You can see this under System Resource Reservation.
Strange place to have that parameter readout.
I can't understand why something that cannot be changed is under the "Configuration" tab and not the "Monitor" or "Summary" tabs.
