Interface Summary

Interface	Description
VmAllocationPolicyMigration	An interface to be implemented by a VM allocation policy that detects Host under and over CPU utilization.
VmAllocationPolicyMigrationDynamicUpperThreshold	An interface to be implemented by VM allocation policies that define a dynamic over utilization threshold computed using some statistical method such as Median Absolute Deviation (MAD), Inter-quartile Range (IQR), Local Regression (LR), etc, depending on the implementing class.

Class Summary

Class	Description
VmAllocationPolicyMigrationAbstract	An abstract VM allocation policy that dynamically optimizes the VM allocation (placement) using migration.
VmAllocationPolicyMigrationBestFitStaticThreshold	A VmAllocationPolicy that uses a Static CPU utilization Threshold (THR) to detect host under and VmAllocationPolicyMigrationStaticThreshold.getOverUtilizationThreshold(Host) over} utilization.
VmAllocationPolicyMigrationDynamicUpperThresholdFirstFit	An abstract class that is the base for implementation of VM allocation policies which use a dynamic over utilization threshold.
VmAllocationPolicyMigrationInterQuartileRange	A VM allocation policy that uses Inter Quartile Range (IQR) to compute a dynamic threshold in order to detect host over utilization.
VmAllocationPolicyMigrationLocalRegression	A VM allocation policy that uses Local Regression (LR) to predict host utilization (load) and define if a host is overloaded or not.
VmAllocationPolicyMigrationLocalRegressionRobust	A VM allocation policy that uses Local Regression Robust (LRR) to predict host utilization (load) and define if a host is overloaded or not.
VmAllocationPolicyMigrationMedianAbsoluteDeviation	A VM allocation policy that uses Median Absolute Deviation (MAD) to compute a dynamic threshold in order to detect host over utilization.
VmAllocationPolicyMigrationStaticThreshold	A VM allocation policy that uses a static CPU utilization threshold to detect host over utilization.
VmAllocationPolicyMigrationWorstFitStaticThreshold	A VmAllocationPolicy that uses a Static CPU utilization Threshold (THR) to detect host under and VmAllocationPolicyMigrationStaticThreshold.getOverUtilizationThreshold(Host) over} utilization.
