Abstract: Described herein are systems, methods, and software to manage configuration attempts for a service following a failure associated with the service according to an implementation. In one example, a management service monitors hosts in a computing environment and identifies a failure associated with a service on a first host. In response to identifying the failure, the management service identifies one or more criteria to initiate an attempt to configure the service based on the type of failure and initiates the attempt to configure the service when the one or more criteria are satisfied. Additional attempts can be initiated by the management service if the initial configuration attempt fails after a timeout interval.

Abstract: An example method of upgrading an application in a software-defined data center (SDDC) includes: deploying, by lifecycle management software executing in the SDDC, a second appliance, a first appliance executing services of the application at a first version, the second appliance having services of the application at a second version, the services in the first appliance being active and the services in the second appliance being inactive; setting, by the lifecycle management software, the first and second appliances as a preemptive pair, where the first appliance is protected and the second appliance is unprotected by fault domain management (FDM) software executing in the SDDC; performing, by the lifecycle management software, a switchover to stop the services of the first appliance and start the services of the second appliance; and setting, by the lifecycle management software, the first appliance as unprotected and the second appliance as protected by the FDM software.

Abstract: Described herein are systems, methods, and software to manage virtual machine shutdowns in a computing environment. In one example, a management service identifies a virtual machine file in a file system associated with a first virtual machine and one or more additional virtual machines and identifies a lock on the virtual machine file by the first virtual machine. The management service further stops execution of the one or more additional virtual machines in response to identifying the lock.
