Logging messages includes providing a logging subsystem that performs logging tasks, providing a log message database that contains log messages that are accessed according to a token value and providing calls to the logging subsystem, where a preprocessor modifies source code to replaces in-line text string parameters with tokens corresponding to the text string parameters. The in-line text string parameters may be log messages. The log message database may be coupled to the logging subsystem and the logging subsystem may access the log messages using the tokens. The preprocessor may determine if an in-line text message already exists in the log message database and, if not, may create a new entry for the in-line text message in the log message database.

In a virtualized environment, provisioned virtual machines may be migrated between different servers as needed and, accordingly, may be clustered according to particular configurations and requirements. The system described herein provides techniques for controlling the provisioning of users' virtual machines among clusters based on determined requirements obtained from users' service level agreements (SLAs) and in accordance with an optimized allocation of resources to service the processes corresponding to the virtual machines. The provisioning of virtual machines according to the system described herein may be dynamically controlled and allow for over-provisioning of virtual machines to a cluster beyond that which would normally be supported at the cluster absent the provisioning control techniques provided by the system described herein. The over-provisioning may be controllable according to specific requirements identified in each user's SLA.

Described is a technique for a backup and restoration of data in a network that includes a multi-lingual file system and a multi-lingual network file server. Multiple meta data files are associated with a single data file in the network. Provided are services for packaging the metadata as a single parameter of an application programming interface (API) for a particular data file being backed up or restored over a network. These techniques may be used in both full and incremental backups and restores of data over a network.
