  • Virtual machine migration with direct physical access control
    Patent number: 9032397
    Abstract: A data processing system facilitates virtual machine migration with direct physical access control. The illustrative data processing system comprises a software-programmable trap control associated with hardware registers of a computer that selectively vectors execution control of a virtual machine (VM) between a host and a guest. The data processing system further comprises a logic which is configured for execution on the computer that programs the trap control to enable the virtual machine to directly access the hardware registers when the virtual machine is not migrated and to revoke direct access of the hardware registers in preparation for virtual machine migration.
    Type: Grant

  • System and method for the management of hardware triggered hotplug operations of input/output cards
    Patent number: 7191275
    Abstract: A method is provided of managing hardware triggered hotplug operations of one or more input/output (I/O) cards of a computer system. The method comprises receiving hardware triggers, each of which relates to a hotplug operation to be carried out on an I/O card associated with a card slot, placing the hardware triggers in a queue, and processing the queue of hardware triggers. The method further comprises processing one or more of said hardware triggers. This comprises analysing a hardware trigger to determine the card slot to which said hardware trigger relates, and consulting a hotplug operation policy to determine whether hotplug operations are enabled for said card slot. If hotplug operations are not enabled for said card slot, this further comprises ignoring said hardware trigger, and if hotplug operations are enabled for said card slot, this further comprise querying said slot to determine whether it contains a card.
