Abstract: A technique is described for handling forks in operations mapped to direct access persistent memory (PMEM). In an example embodiment, access by a parent operation of an allocated portion of PMEM is monitored to determine a portion of the allocated PMEM that is in use by the parent operation. In response to a fork call indicating that the parent operation will copy itself to create a child operation, a clone of the portion of allocated PMEM is created to facilitate processing of the child operation. The cloned portion of PMEM can be created just before the child operation is created (i.e., pre-fork) or after the child operation is created (i.e., post-fork). To create the clone post-fork, a user-space page fault notification mechanism can be implemented to detect a next buffer access by the child operation and create the clone in response to the detected access.

Abstract: A new approach to virtual desktop infrastructure management is described. In one example, a master virtual machine is configured to form a master image. The master virtual machine and master image are also modified to incorporate a service that performs an enrollment call to an endpoint manager associated with a virtual desktop infrastructure. One or more virtual machines are instantiated using the master image. When one of the virtual machines is booted and a user logs on, the service is invoked or executed and performs the enrollment call. The enrollment call leads to the enrollment of the virtual machine with the endpoint manager. During and after enrollment, the endpoint manager can configure the virtual machine based on one or more management policies. The management policies can be tailored in various cases, such as depending upon the credentials used to log on to the virtual machine.

Abstract: A host machine includes a guest machine, a device emulator, and a hypervisor communicably coupled to the guest machine and the device emulator. The guest machine executes a non-real time thread that causes a non-real time I/O emulation by the device emulator. Responsive to receipt of a real time thread by the guest machine, the hypervisor determines whether the non-real time I/O emulation is abortable or non-abortable. If abortable, the hypervisor aborts the non-real time thread and causes the guest machine to execute the real time thread. Upon completing the execution of the real time thread, the hypervisor causes the guest machine to revert to a non-real time context based on a previous system snapshot. Upon establishing the non-real time context, the hypervisor causes the guest machine to execute the previously aborted non-real time thread.
