Placement of virtual machines on physical hosts is based on collocation rules with situational enforcement policies set by a system administrator to increase flexibility in rule enforcement and to more efficiently utilize system resources. A scheduler mechanism allows a system administrator to select different collocation rules and situational enforcement policies for a group of virtual machines. The scheduler mechanism utilizes the collocation rules and the situational enforcement policies to place the virtual machines.

Dynamically setting the order of optimization of physical hosts allows more efficient and varied optimization. An ordering policy mechanism utilizes ordering policies to set an order for the optimizer to optimize physical the hosts. The ordering policy mechanism may allow a system administrator to create and/or select ordering policies. The ordering policies may include fixed ordering policies or dynamic ordering policies.

Ordering optimization of host machines in a computing environment based on policies

Mechanisms are provided for translating messages output by processes associated with the data processing system. Language based user activities occurring via a data processing system are tracked and automatically analyzed to determine a relative priority ordering of one or more languages used by a user performing the user activities. A sequence of preferred language translation substitutions is generated for outputting messages based on results of the analysis and is automatically applied to a received message from a process associated with the data processing system to generate a translated message using one of the preferred language translation substitutions in the sequence of preferred language translation substitutions. The translated message is output via an output device of the data processing system.

Systems, methods, and computer program products configured to perform an operation comprising determining that use of a system resource of a first host system exceeds a threshold, wherein the first host system executes a plurality of virtual machines in a cloud computing environment, identifying a first virtual machine, of the plurality of virtual machines, for migration based on a first migration policy, of a plurality of migration policies, wherein the plurality of migration policies specify a respective set of rules for identifying virtual machines for migration, and migrating the first virtual machine to a second host system in the cloud computing environment to reduce the use of the system resource on the first host system.

Policy based virtual machine selection during an optimization cycle

Dynamically changing the aggressiveness of optimization of virtual machines on physical hosts allows more efficient and varied optimization. An aggressiveness policy mechanism periodically applies system conditions to the aggressiveness policies to create aggressiveness settings that are provided to an optimizer. The optimizer then uses the aggressiveness settings to dynamically adjust the aggressiveness of placement of virtual machines according to the aggressiveness settings and consistent with other optimization policies. The aggressiveness policy mechanism may allow a system administrator to create and/or select aggressiveness policies.

Dynamic aggressiveness for optimizing placement of virtual machines in a computing environment

Disclosed aspects include managing asset placement with respect to a shared pool of configurable computing resources. A first set of first resource values is detected with respect to a set of assets. The first set of first resource values includes a first value. A second set of first resource values is detected with respect to the set of assets. The second set of first resource values includes a second value. The second value exceeds the first value. A set of asset weight values is detected with respect to the set of assets. The set of asset weight values indicates an asset utilization arrangement. A placement arrangement is determined for the set of assets using the first set of first resource values, the second set of first resource values, and the set of asset weight values. Accordingly, the set of assets is placed based on the placement arrangement.

Managing asset placement with respect to a shared pool of configurable computing resources

Placement of virtual machines on physical hosts is based on a preferred host list that may be generated from preferred host identifiers to more efficiently utilize system resources and serve the needs of different workloads. A host identifiers mechanism allows a system administrator to select preferred host identifiers for each virtual machine or a group of virtual machines. The host identifiers mechanism in conjunction with an optimizer periodically adjusts the placement of virtual machines according to the preferred host identifiers and consistent with optimization policies. Further, the preferred host identifiers may include a time component so that the preferred host resources can be periodically updated and can dynamically change over time.
