Abstract: Systems and methods for managing deployment of an update to computing devices, and for diagnosing issues with such deployment, are provided. An update deployment manager determines one or more initial computing devices to receive and execute an update. The update deployment manager further monitors a set of performance metrics with respect to the initial computing devices or a collection of computing devices. If a deployment issue is detected based on the monitored metrics, the update deployment manager may attempt to diagnosis the deployment issue. For example, the update deployment manager may determine that a specific characteristic of computing devices is associated with the deployment issue. Thereafter, the update deployment manager may modify future deployment based on the diagnosis (e.g., to exclude computing devices likely to experience the deployment issue).

Abstract: Physical (or prior virtual) machine volumes can be converted to virtual machines at a virtual machine host while the physical machines are running. In one implementation, a volume shadow copy service can be used to create an application (and/or file system)-consistent snapshot of one or more physical machine volumes while the one or more volumes are running. The snapshot data can then be transferred to a mounted virtual hard disk file (dynamic or fixed) at a virtual machine host. Operational information (e.g., boot record, system registry, drivers, devices, configuration preferences, etc.) associated with the virtual hard disk file and the operating system(s) within the virtual machine can then be modified as appropriate to ensure that the corresponding virtual machine is bootable and functional at the virtual machine host. The virtual hard disk file can then be un-mounted, and used as a new virtual machine.
