A virtual category type reservation provides access to the provisioning services of a virtual machine deployment for a particular vRealize Automation business group. Available virtual reservation types include vSphere, Hyper-V, KVM, SCVMM, and XenServer.

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

A business group can have multiple reservations on one endpoint or reservations on multiple endpoints.

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