Abstract: The present disclosure involves systems, software, and computer implemented methods for identifying traits of an object. In one example, a set of traits is identified in an object-oriented system. A set of trait rules is identified. A trait data structure is generated. A set of classes in the object-oriented system is identified. For each class in the set of classes, a metadata structure is constructed. For each trait in the trait data structure, a trait rule in the trait computation rules structure is identified. The trait rule is applied to the particular metadata structure to generate a trait rule result. Whether the particular class has the particular trait is determined based on the trait rule result. In response to a determination that the particular class has the particular trait, the trait data structure is updated. The updated trait data structure indicates that the particular class has the particular trait.

The estimated time is compared to a threshold time and based on the estimated time meeting the threshold time, a migration of the VM from the source hypervisor to the target hypervisor via the network is initiated. Based on the estimated time not meeting the threshold time, it is determined whether an additional path can be added to the network between the source hypervisor and the target hypervisor. If an additional path cannot be added to the network, a migration of the VM from the source hypervisor to the target hypervisor via the network is initiated. If an additional path can be added to the network, the additional path is added and the migration via the network is initiated.
