Abstract: Systems and methods for optimizing a virtual machine cluster. An example method may comprise receiving, by a processing device, an information characterizing a virtual machine cluster, the information comprising at least one of: values of one or more cluster configuration parameters, values of one or more cluster state parameters, or values of one or more user request parameters; and producing, in view of the received information, an ordered list of cluster configuration operations to be performed on virtual machines of the virtual machine cluster, the cluster configuration operations designed to yield a resulting configuration of the virtual machine cluster, wherein the resulting configuration is characterized by a quasi-optimal configuration score among configuration scores of two or more candidate configurations, the configuration score determined by applying one or more virtual machine scheduling policy rules to parameters of a candidate configuration.

Abstract: A method relates to identifying, by a processing device, a bug ticket stored in a data record, wherein the bug ticket is associated with a patch comprising code to fix a bug described in the bug ticket, and wherein the bug ticket comprises a version flag indicating whether the bug ticket receives all of a plurality of acknowledgements, determining, in view of a value of the version flag, that the bug ticket does not include an acknowledgement required to place the patch into a production repository, determining, in view of a set of acknowledgement flags of the bug ticket, an entity responsible for providing the acknowledgement, and transmitting a notification to the entity, wherein the notification comprises a hyperlink linked to a user interface page to provide the acknowledgement by the entity.

Abstract: A processing device receives a rule for execution by a rules engine and provides the rule to the rules engine. The processing device receives a request to provision a virtual machine (VM) having VM attributes. The processing device provides metrics of a plurality of physical hosts to the rules engine and the VM attributes to the rules engine. The processing device then receives. from the rules engine, an identification of one or more prioritized physical hosts of the plurality of physical hosts. The processing device provisions the VM on one of the one or more prioritized physical hosts.
