A management system and method that generally allocates a virtual function to a virtual function definition of a virtual server, where the virtual function definition of the virtual server is previously assigned with a unique function identifier, and assigns the unique function identifier to the virtual function in response to the allocating of the virtual function, where the unique function identifier causes a discovery of the virtual function by the virtual server.

Supporting flexible deployment and migration of virtual servers via unique function identifiers

A computer-implemented method, carried out by one or more processors, for policy based virtual resource allocation. In an embodiment, the method includes identifying a number of host resources specified by host resource requirements for a first resource consumer. The method determines if the host resource requirements include a list of host resource pools for the first resource consumer. Responsive to determining that the host resource requirements include the list of host resource pools for the first resource consumer, a first set of eligible host resource pools is identified. An allocation policy may be identified, where the allocation policy includes one or more parameters for allocating host resources. Host resources from the first set of eligible host resource pools are allocated based on the allocation policy.

Policy based virtual resource allocation and allocation adjustment

A method for managing resources in a server environment includes querying a first resource consumer for a list, wherein the list includes at least a first virtual resource and a first host resource. The method queries a host resource pool to determine if the first host resource is present. Responsive to determining the first host resource is present in the host resource pool, the method allocates the first host resource to the first resource consumer. The method sends a request to activate the first virtual resource and the first host resource to a virtual resource provider and a host resource provider, wherein the request to activate the first virtual resource and the first host resource is performed on a single thread. The method determines to prepare one or more virtual resources for activation of one or more allocated host resources.

Resource allocation/de-allocation and activation/deactivation

A computer-implemented method, carried out by one or more processors, for managing resources in a server environment. The method includes determining, by one or more processors, to shut down a first resource consumer, wherein the first resource consumer is assigned a first virtual resource with a first set of one or more host resources. It is determined, by one or more processors, whether a second virtual resource assigned to a second resource consumer requires the first set of one or more host resources. If the second virtual resource assigned to the second resource consumer does not require the first set of one or more host resources, it is determined, by one or more processors, not to deactivate the one or more host resources assigned to the first virtual resource.

Anticipatory resource allocation/activation and lazy de-allocation/deactivation

A computer-implemented method, carried out by one or more processors, for managing resources in a server environment. In an embodiment, the method includes determining to prepare one or more virtual resources for activation of one or more allocated host resources, based, at least in part, on virtual resource definitions. The one or more allocated host resources and the one or more virtual resources are activated. Activation of the one or more virtual resources is finalized, wherein finalizing the activation includes updating the virtual resource definitions.
