Abstract: Distributed tracing is applied during an upgrade from a first management appliance to a second management appliance. The distributed tracing method includes generating a parent span that encapsulates states of the overall workflow, including a span context that contains a trace identifier and a span identifier, and generating a plurality of child spans. Each child span encapsulates states that represent a piece of the workflow and contains a reference to the parent span context. The states of the child spans include an error tag that indicates whether the piece of the workflow associated with the child span executed with an error. Because child spans may be generated for a piece of the workflow that is executed by a service running in the first or second management appliance, the span context for the parent span is persisted by the first management appliance and replicated for use by the second management appliance.

Abstract: A method performing at least one of hardware component compatibility checks or resource checks for datastore deployment is provided. The method includes receiving a request to aggregate local disks of a first host in a first host cluster to create and deploy a first datastore for the first host cluster, determining one or more of hardware components on the first host supports the deployment of the first datastore using a first database file available on the first host or resources on the first host support the deployment of the first datastore, and aggregating the local disks of the first host to create and deploy the first datastore for the first host cluster based on the determination.

Abstract: A host computing system may include a processor and a memory coupled to the processor. The memory may include an auto-discovery module to broadcast a message to a set of management nodes in a data center. The message may include a configuration policy. Further, the auto-discovery module may receive an acknowledgment message from a management node. The acknowledgment message may indicate that the management node supports the configuration policy. Furthermore, the auto-discovery module may establish a trust relationship with the management node in response to receiving the acknowledgment message. Further, the auto-discovery module may enable the host computing system to add to a cluster managed by the management node upon establishing the trust relationship.

Abstract: Techniques for declaratively deploying a virtual infrastructure management (VIM) server in a computing environment are provided. According to one set of embodiments, an installer computer system can receive a desired state definition specifying a desired state for the VIM server and a virtual infrastructure to be managed by the VIM server. The installer computer system can further install the VIM server on a target computer system in the computing environment and provide the desired state definition to the target computer system. Upon initial boot up of the VIM server on the target computer system, a service of the VIM server can automatically configure the VIM server in accordance with the desired state definition.
