A virtual reservation is a share of the memory, CPU, networking, and storage resources of one compute resource allocated to a particular business group.

To provision virtual machines, a business group must have at least one reservation on a virtual compute resource. Each reservation is for one business group only, but a business group can have multiple reservations on a single compute resource, or multiple reservations on compute resources of different types.

In addition to the share of fabric resources allocated to the business group, a reservation can define policies, priorities, and quotas that determine machine placement.
