Abstract: A graphical user interface (GUI) may be provided. The GUI may include a navigation tree in a first portion and a link in a second portion. The navigation tree may include multiple nodes. A selection of the link in the section portion may be received. In response to the selection of the link, the navigation tree in the first portion may be expanded to a hierarchical level displaying the node corresponding to the selected link.

Abstract: An apparatus identifies a connector configuration event. Responsive to the connector configuration event, the apparatus sends an external service information request. The apparatus receives an external service reply to the external service information request. The apparatus performs connector configuration, wherein the connector configuration employs information included in the external service reply, and wherein the performing connector configuration yields a connector employable in consumer external service access.

Abstract: Clients access compute resources in a data center organized in logical clusters. A cluster level quota governs access to the compute resources, regardless of the location of the resources which can be part of multiple computers or part of multiple data centers. The cluster level quota can manage allocation and usage of storage, memory, and CPU resources in multi-tenant data center environments. A user requests a computing resource from a logical compute cluster in a data center of host machines hosting virtual machines. According to permissions associated with the user for the logical compute cluster and a cluster quota, the system grants access to the computing resource to the user in response to the request when the cluster quota permits an expected use of the computing resource according to the request.

Abstract: The subject matter of this specification can be implemented in, among other things, a computer-implemented method including sending, from a virtual desktop server manager at a data center and over a network, at least one request to a virtual machine storage domain for virtual machine installation images. The virtual machine storage domain stores the virtual machine installation images separate from the data center. The method further includes receiving, from the virtual machine storage domain over the network, the virtual machine installation images. The method further includes caching the virtual machine installation images in a data storage domain within the data center. The method further includes receiving a request to present a list of the virtual machine installation images. The method further includes in response to receiving the request to present the list, presenting the list of the cached virtual machine installation images.

Abstract: A host controller generates and sends a request for first status information to a host. The host controller receives first status information from the host along with a unique identifier that is associated with the first status information. After a time period, the host controller generates and sends a new request for second status information to the host, the new request including the unique identifier. When second status information and the first status information are associated with the same unique identifier, the host controller receives a response from the host indicating that the second status information is the same as the first status information.
