The graphs on the right show a summary of the available resources in this Host. Hosts provide CPU and RAM resources to Guests. The total resources offered by a Host consist of its physical resources adjusted by an overcommit factor. By overcommiting, a Host can offer more resources than actually available. A CPU overcommit of 2, or three, can generally be safely used, because most of the time guests do not use more than 30-50% of their available CPU power. RAM overcommit is generally discouraged.

Resources must be first reserved by a Pool, then used by a Guest of the Pool. The bar graphs show how much resources are in use by Guests, how much are free, and how much are not reserved by any Pool. Next to the graphs there is also the same information in numeric form, and a relation of physical and overcommited resources.
