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.
- Move database access code to new class DatabaseAccessObject.
This was done to ease the effort of testing, since
DbUpgradeUtils has a static API and it is harder to mock

service and not used for LB
Fix adds a boolean flag to addNetscalerLoadBalancer api, which
will mark added NetScaler for exclusive GSLB service. A netscaler marked
as exclusive gslb service provider is not picked for any guest network's
lb provider.
scaling up vms was not considering parameter cluster.(memory/cpu).allocated.capacity.disablethreshold. Fixed it
Also added overprovisioning factor retrieval at the cluster level for host capacity check
This patch adds support for trust chains in the netscaler.
I initially planned on using the 10.1 API's "bundle" feature but during
my testing I found that was not working. So I am doing the chain linking
myself. Also NS can have only one entity of a certificate ie lets say
two different users try to add the same certificate on the netscaler
only one of them will go through. The other one says resouce already
exists even though they have different files.
This can be a problem in trust chains where the chain can be shared
between multiple accounts/certificates. So, I am using the figerprint as
an identifier of a certificate and making sure that we delete it only
when no one references it.
Resource limit shouldnt be counted for resources with display flag = 0. Adding functions to resourcelimitmanager and doing it for the volumes at the moment.
used cpu is getting bumped up when the over provisioning factor > 1. This was because we didnt record the overprovisioning factors of the vms which got deployed pre 4.2
Upgrade path will fix that by populating the cpu/mem overprovisioning factors for each of the vms in user_vm_details table using the global overprovisioning factor.

Introduction of a new Transaction API that is more consistent with the style
of Spring's transaction managment. The existing Transaction class was renamed
to TransactionLegacy. All of the non-DAO code in the management server has been
updated to use the new Transaction API.
When running DatabaseUpgradeChecker as a standalone program _dao will not
be injected. Still create an instance of VersionDaoImpl in constructor
and when DatabaseUpgradeChecker is ran in the mgmt server it will be
overwritten by the injected value.
ACS is now comprised of a hierarchy of spring application contexts.
Each plugin can contribute configuration files to add to an existing
module or create it's own module.
Additionally, for the mgmt server, ACS custom AOP is no longer used
and instead we use Spring AOP to manage interceptors.
Also fixed existing bugs for the API:
* corrected action event to be VOLUME.UPDATE (was VOLUME.ATTACH)
* all parameters to update, should be optional - fixed that. If nothing is specified, the db object will remain with its original fields
Check for the all the transition states for Maintenance. Also corrected the isMaintenance function for StoragePoolVo

Description:
Set the criterion for overriding/preserving the vmware.create.full.clone
flag so that if past version deployments have any deployments (data centers),
this flag will be set to false. Else, it will be set to true.
The earlier criterion to set this flag was based on the CS version numbers,
but that is not a good business logic to serve as a basis to set the flag.
Changes:
- In the upgrade path, for a private zone, entry needs to be added in the affinity_group_domain_map to provide access to the private zone for the domains it belongs too.
Changes:

- Only one group per account or per domain will be present
- ListDedicatedResources by affinityGroup
- Deployment should consider dedicated resources associated to the group only
- Deleting affinity group should release the dedicated resouces
- Releasing the dedicated resources should remove the group associated if there are no more resources.

While upgrading to 4.2, the type of vswitch being used by each cluster is persisted to cluster_details table. This helps if user want to change the type of vswitch used in a zone or entire cloud later on but leave existing cluster continue to use old vswitches. Hence even after modifying the type of vswitch at cloud level (by modifying global configuration parameters) or modifying the type vswitch at zone level (by modifying the traffic label) would not disturb operation of existing clusters.

Updating the new system template URLs for the existing templates during upgrade to 4.2.
If new 4.2 system template is registered before upgrade then marking the old templates as removed during upgrade.
The time increased due to the newly added dedicated resources feature. During regular VM deployment, all dedicated resources are put in avoid list so that they are not considered for deployment.
Now the way to compute the list of dedicated resources is not optimal and performance deteriorates in an environment having lot of pods, clusters and hosts as the logic is to query db. for each suc resource.
The fix is to optimize the logic not to loop through all resources but get the list of each resource type in a single query.

- This causes the disconnect task to get NPE while trying to do the host state transition

- Made host scan task interval configurable
only on first rule is created on the IP and last rule is revoked on the
IP
Current suboptima logic of IP Assoc
- On associate IP to GuestNetwork there is an IPAssoc command sent to
corresponding network service providers of the network
- On every rule apply on IP associated with the network send IP assoc
to the network service providers
- On every rule deletion on IP associated with a network sernd IP assoc
command to the network service providers
With this fix logic of IP assoc is changed as below which eliminates
executio of unnessary and expensive IpAssocCommand resource command
- On associate IP to GuestNetwork, associate IP only to the network,
Untill any service is associated with the IP dont send IP Assoc
- On creation of first rule on the IP send IPAssoc to corresponding
network service provider. Since IP is used for a service, IPAssoc
need to be sent to correpondign service provider
- On deletion of last rule on the IP send IPAssoc to corresponding
network service provider. When last rule is deleted, IP has no
service associated with it, so send IP assoc to service provider to
remove the IP association

This feature allows a user to deploy VMs only in the resources dedicated to his account or domain.
1. Resources(Zones, Pods, Clusters or hosts) can be dedicated to an account or domain.
Implemented 12 new APIs to dedicate/list/release resources:
- dedicateZone, listDedicatedZones, releaseDedicatedZone for a Zone.
- dedicatePod, listDedicatedPods, releaseDedicatedPod for a Pod.
- dedicateCluster, listDedicatedClusters, releaseDedicatedCluster for a Cluster
- dedicateHost, listDedicatedHosts, releaseDedicatedHost for a Host.
2. Once a resource(eg. pod) is dedicated to an account, other resources(eg. clusters/hosts) inside that cannot be further dedicated.
3. Once a resource is dedicated to a domain, other resources inside that can be further dedicated to its sub-domain or account.
4. If any resource (eg.cluster) is dedicated to a account/domain, then resources(eg. Pod) above that cannot be dedicated to different accounts/domain (not belonging to the same domain)
5. To use Explicit dedication, user needs to create an Affinity Group of type 'ExplicitDedication'
6. A VM can be deployed with the above affinity group parameter as an input.
7. A new ExplicitDedicationProcessor has been added which will process the affinity group of type 'Explicit Dedication' for a deployment of a VM that demands dedicated resources.
This processor implements the AffinityGroupProcessor adapter. This processor will update the avoid list.
8. A VM requesting dedication will be deployed on dedicatd resources if available with the user account.
9. A VM requesting dedication can also be deployed on the dedicated resources available with the parent domains iff no dedicated resources are available with the current user's account or
domain.
10. A VM (without dedication) can be deployed on shared host but not on dedicated hosts.
11. To modify the dedication, the resource has to be released first.
12. Existing Private zone functionality has been redirected to Explicit dedication of zones.
13. Updated the db upgrade schema script. A new table "dedicated_resources" has been added.
14. Added the right permissions in commands.properties
15. Unit tests: For the new APIs and Service, added unit tests under : plugins/dedicated-resources/test/org/apache/cloudstack/dedicated/DedicatedApiUnitTest.java
16. Marvin Test: To dedicate host, create affinity group, deploy-vm, check if vm is deployed on the dedicated host.
