Feature spec: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Granular+Resource+Limit+Management
Introduces the concept of tagged resource limits for granular resource limit management. Limits can be enforced on accounts and domains for the deployment of entities for a tagged resource. Current tagged resource limits can be used for the following resource types,
Host limits
- user_vm
- cpu
- memory
Storage limits
- volume
- primary_storage
Following global settings can used to specify tags for which limit needs to be enforced,
Host: `resource.limit.host.tags`
Storage: `resource.limit.storage.tags`
Option for specifying tagged resource limits and viewing tagged resource usage are made available in the UI.
Enhances the use of templatetag for VM deployment and template creation
Adds option to list service/compute offerings that can be used with a given template. A new parameter named templateid has been added.
Adds option to list disk offering with suitability flag for a virtual machine. A new parameter named virtualmachineid has been added to the listDiskOfferings API which when passed returns suitableforvirtualmachine param in the response.
This PR addresses parallel resource allocation as a generalization of the problem and solution described in #6644. Instead of the Global lock on the resources a reservation record is created which is added in the resource check count in the ResourceLimitService/ResourceLimitManagerImpl. As a convenience a CheckedReservation is created. This is an implementation of AutoClosable and can be used as a guard in a try-with-resource fashion. The close method of the CheckedReservation wil delete the reservation record.
