CLOUDSTACK-4762 : Enabling VGPU support for XenServer.
This feature is to enable the GPU-passthrough and vGPU functionality,
with the help of this feature, admins/users will be able to leverage
the GPU graphics unit power by deploying a virtul machine with GPU or
vGPU support or by changing the service offering of an existing VM
at any later point of time. There GPU/vGPU enabled VMs are able to run
graphical applications.
For now, this feature is only supported with XenServer hypervisor but
can be extended to add the support of other hypervisors.
Removing memoryovercommitratio and cpuovercommitratio parameters from addCluster and updateCluster APIs,
since these can be configurable using updateConfiguration API at cluster level.
By default while creating cluster these values are taken from global configuration parameters.
- Changes merged from planner_reserve branch
- Exposing deploymentplanner as an optional parameter while creating a service offering
- changes to DeploymentPlanningManagerImpl to make sure host reserve-release happens between conflicting planner usages.
