About Virtual Machine Quotas
For self-service users who are allowed to create their own virtual machines, you can limit the number of virtual machines that the users can deploy at one time by setting a virtual machine quota in the self-service policy.
The application of quota points. Virtual machines can vary greatly in the amount of disk space and resources they require. To account for these variations, you can assign a different number of quota points to different virtual machines. This is configured on the virtual machine templates that self-service users use to create their computers.
The quota points apply only to virtual machines that are deployed on a host. If the users are allowed to store their virtual machines when they are not in use, the virtual machines that are stored do not count against their quota.
Shared vs. per user ownership for groups. If the self-service policy applies to a user account, the quota applies to all deployed virtual machines that the user owns. However, if the self-service policy applies to a group, the quota can be implemented under shared ownership or per user ownership:
Under shared ownership, all members of the group own, operate, and manage all virtual machines that are created by the group according to the virtual machine permissions in the self-service policy. If a virtual machine quota is set in the self-service policy, a single quota is applied to all virtual machines deployed by the group.
Under individual ownership, each member of the group owns and manages his own virtual machines; other group members cannot see or operate the virtual machines. If a virtual machine quota is set in the self-service policy, the quota applies to each group member individually.
