* api,agent,server,engine-schema: scalability improvements
Following changes and improvements have been added:
- Improvements in handling of PingRoutingCommand
1. Added global config - `vm.sync.power.state.transitioning`, default value: true, to control syncing of power states for transitioning VMs. This can be set to false to prevent computation of transitioning state VMs.
2. Improved VirtualMachinePowerStateSync to allow power state sync for host VMs in a batch
3. Optimized scanning stalled VMs
- Added option to set worker threads for capacity calculation using config - `capacity.calculate.workers`
- Added caching framework based on Caffeine in-memory caching library, https://github.com/ben-manes/caffeine
- Added caching for account/use role API access with expiration after write can be configured using config - `dynamic.apichecker.cache.period`. If set to zero then there will be no caching. Default is 0.
- Added caching for account/use role API access with expiration after write set to 60 seconds.
- Added caching for some recurring DB retrievals
1. CapacityManager - listing service offerings - beneficial in host capacity calculation
2. LibvirtServerDiscoverer existing host for the cluster - beneficial for host joins
3. DownloadListener - hypervisors for zone - beneficial for host joins
5. VirtualMachineManagerImpl - VMs in progress- beneficial for processing stalled VMs during PingRoutingCommands
- Optimized MS list retrieval for agent connect
- Optimize finding ready systemvm template for zone
- Database retrieval optimisations - fix and refactor for cases where only IDs or counts are used mainly for hosts and other infra entities. Also similar cases for VMs and other entities related to host concerning background tasks
- Changes in agent-agentmanager connection with NIO client-server classes
1. Optimized the use of the executor service
2. Refactore Agent class to better handle connections.
3. Do SSL handshakes within worker threads
5. Added global configs to control the behaviour depending on the infra. SSL handshake could be a bottleneck during agent connections. Configs - `agent.ssl.handshake.min.workers` and `agent.ssl.handshake.max.workers` can be used to control number of new connections management server handles at a time. `agent.ssl.handshake.timeout` can be used to set number of seconds after which SSL handshake times out at MS end.
6. On agent side backoff and sslhandshake timeout can be controlled by agent properties. `backoff.seconds` and `ssl.handshake.timeout` properties can be used.
- Improvements in StatsCollection - minimize DB retrievals.
- Improvements in DeploymentPlanner allow for the retrieval of only desired host fields and fewer retrievals.
- Improvements in hosts connection for a storage pool. Added config - `storage.pool.host.connect.workers` to control the number of worker threads that can be used to connect hosts to a storage pool. Worker thread approach is followed currently only for NFS and ScaleIO pools.
- Minor improvements in resource limit calculations wrt DB retrievals

This pull request (PR) implements a Distributed Resource Scheduler (DRS) for a CloudStack cluster. The primary objective of this feature is to enable automatic resource optimization and workload balancing within the cluster by live migrating the VMs as per configuration.
Administrators can also execute DRS manually for a cluster, using the UI or the API.
Adds support for two algorithms - condensed & balanced. Algorithms are pluggable allowing ACS Administrators to have customized control over scheduling.
Implementation
There are three top level components:
Scheduler
A timer task which:
Generate DRS plan for clusters
Process DRS plan
Remove old DRS plan records
DRS Execution
We go through each VM in the cluster and use the specified algorithm to check if DRS is required and to calculate cost, benefit & improvement of migrating that VM to another host in the cluster. On the basis of cost, benefit & improvement, the best migration is selected for the current iteration and the VM is migrated. The maximum number of iterations (live migrations) possible on the cluster is defined by drs.iterations which is defined as a percentage (as a value between 0 and 1) of total number of workloads.
Algorithm
Every algorithms implements two methods:
needsDrs - to check if drs is required for cluster
getMetrics - to calculate cost, benefit & improvement of a migrating a VM to another host.
Algorithms
Condensed - Packs all the VMs on minimum number of hosts in the cluster.
Balanced - Distributes the VMs evenly across hosts in the cluster.
Algorithms use drs.level to decide the amount of imbalance to allow in the cluster.
APIs Added
listClusterDrsPlan
id - ID of the DRS plan to list
clusterid - to list plans for a cluster id
generateClusterDrsPlan
id - cluster id
iterations - The maximum number of iterations in a DRS job defined as a percentage (as a value between 0 and 1) of total number of workloads. Defaults to value of cluster's drs.iterations setting.
executeClusterDrsPlan
id - ID of the cluster for which DRS plan is to be executed.
migrateto - This parameter specifies the mapping between a vm and a host to migrate that VM. Format of this parameter: migrateto[vm-index].vm=<uuid>&migrateto[vm-index].host=<uuid>.
Config Keys Added
ClusterDrsPlanExpireInterval
Key drs.plan.expire.interval
Scope Global
Default Value 30 days
Description The interval in days after which old DRS records will be cleaned up.
ClusterDrsEnabled
Key drs.automatic.enable

Description The interval in minutes after which a periodic background thread will schedule DRS for a cluster.
ClusterDrsIterations
Key drs.max.migrations
Scope Cluster
Default Value 50
Description Maximum number of live migrations in a DRS execution.
ClusterDrsAlgorithm
Key drs.algorithm
Scope Cluster
Default Value condensed
Description DRS algorithm to execute on the cluster. This PR implements two algorithms - balanced & condensed.
ClusterDrsLevel
Key drs.imbalance
Scope Cluster
Default Value 0.5
Description Percentage (as a value between 0.0 and 1.0) of imbalance allowed in the cluster. 1.0 means no imbalance
is allowed and 0.0 means imbalance is allowed.
ClusterDrsMetric
Key drs.imbalance.metric
Scope Cluster
Default Value memory
Description The cluster imbalance metric to use when checking the drs.imbalance.threshold. Possible values are memory and cpu.
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration
- remove custom <build> configuration in pom.xml

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.
Changes:
- Adding mocks in unit tests for new injected components
Conflicts:
server/test/org/apache/cloudstack/networkoffering/ChildTestConfiguration.java
Changes:
- Implict creation of the 'ExplicitDedication' Affinity group during resource dedication
- 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.
Conflicts:
plugins/dedicated-resources/src/org/apache/cloudstack/dedicated/DedicatedResourceManagerImpl.java
plugins/dedicated-resources/test/org/apache/cloudstack/dedicated/manager/DedicatedApiUnitTest.java
server/src/com/cloud/configuration/ConfigurationManagerImpl.java
Changes:
- 'ExcplicitDedication' type of group can be created/deleted by Root admin only
- Users can no longer create this type of affinity group
- RootAdmin can create this type of affinitygroup at domain level. Such a domain level group is available for all accounts in that domain for listing and for use during deployVM.
- The domain level affinitygroup should be visible to the users in that domain, domain admins and Root admin.

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.
