The present invention provides a data processing system with multiple logical partitions that isolate memory resources for applications contained in the logical partitions. A method is provided for moving a specific memory quantity between two logical partitions by first computing a threshold amount. Then, if the specific memory quantity to be transferred is less than the threshold amount, removing the threshold amount from memory assigned in the first partition and adding the threshold amount to memory assigned in the second partition. However, if the specific memory quantity is greater than the threshold amount, the method provides for removing an amount equal to the threshold from memory assigned in the first partition and adding that threshold amount to memory assigned in the second partition and repeating the removing and adding steps until the specific memory quantity has been transferred.

A switch is provided that detects when a computer expansion card has been added, removed or changed. During operation, the switch is held in a depressed position by contact with a card. If the card is removed, the switch is raised and, when a second card is installed in the same slot, the switch is again depressed. The depression of the switch triggers a change signal that initiates the introduction of power to the slot for a period of time long enough for the hypervisor to detect the new device. A delay between a release and subsequent depression of the switch is measured such that when the switch is released enough time is provided to firmly seat a different card in the planar device. Following the delay, power is supplied to the slot so that the hypervisor detects the card and updates the current configuration parameters.

Methods and arrangements of monitoring applications active on a plurality of computers are discussed. Embodiments include transformations, code, state machines or other logic to connect a plurality of computing devices via a keyboard video mouse (KVM) switch and to detect applications active on the computing devices. In some embodiments, each computing device may be connected to a display separate from the KVM switch. The embodiment may include detecting applications signaling a user for attention and displaying a list of active applications of the plurality of computing devices in response to a command from the user. The displaying may include giving priority to the applications signaling a user for attention.
