    摘要： A system and method for enabling hot-plugging of devices in virtualized systems. A hypervisor obtains respective values representing respective quantities of a resource for a plurality of virtual root buses of a virtual machine (VM). The hypervisor determines a first set of address ranges of the resource that are allocated for one or more virtual devices attached to at least one of the plurality of virtual root buses. The hypervisor determines, in view of the first set of allocated address ranges, a second set of address ranges of the resource available for attaching one or more additional virtual devices to at least one of the plurality of virtual root buses. The hypervisor assigns to the plurality of virtual root buses non-overlapping respective address ranges of the resource within the second set.

    摘要： Methods and systems for identifying a set of disks within a cluster and then storing a plurality of data chunks into the set of disks such that the placement of the plurality of data chunks within the cluster optimizes failure tolerance and storage system performance for the cluster are described. The plurality of data chunks may be generated using replication of data (e.g., n-way mirroring) or application of erasure coding to the data (e.g., using a Reed-Solomon code or a Low-Density Parity-Check code). The topology of the cluster including the physical arrangement of the nodes and disks within the cluster and status information for the nodes and disks within the cluster (e.g., information regarding disk fullness, disk performance, and disk age) may be used to identify the set of disks in which to store the plurality of data chunks.

    摘要： A hybrid account logon is disclosed for logging into remote desktops. In one embodiment, the hybrid logon combines local and domain accounts by building a local primary access token which provides credentials for local and domain-based accounts. In one embodiment, a credentials provider creates a serialized structure including both local account information and domain credentials and sends the serialized structure to a logon user interface (UI) process. The logon UI process calls a user authentication service that itself calls a hybrid authentication package which performs a domain logon, discards any identity associated with the domain logon session, and builds a local identity for the local account. The user authentication service then generates a primary access token including the local identity and the domain logon session data, thereby supporting interactive logon based on the local user identity which is also linked to network credentials for use in accessing network resources.
