摘要： In a virtualized system running one or more virtual machines on a first hypervisor, a second hypervisor is installed and control of the hardware resources of the physical computer supporting the virtualized system is migrated from the first hypervisor to the second hypervisor without interrupting the operation of the first hypervisor and the virtual machines. Initially a minimal set of hardware resources is hot-removed from control by the first hypervisor, and the second hypervisor is launched on the minimal set of hardware resources. Both the remaining hardware resources and the virtual machines are then migrated from the first hypervisor to the second hypervisor until all the virtual machines have been migrated over to the second hypervisor, while the virtual machines and the first hypervisor continue running largely unaffected by the migration process.

摘要： A method of determining compatibility of a virtual machine or virtual machine disk file with a host, including a storage host, is disclosed. A lookup matrix is created to provide a fast compatibility lookup for a group of computing objects and a group of hosts. To create the lookup matrix, computing object properties are retrieved from each of the plurality of computing objects. The computing object properties include resource requirements of each of the plurality of computing objects. Further, host properties are retrieved from each of the plurality of hosts. The method further includes creating a plurality of host logical groups of a subset of the plurality of hosts having substantially same host properties and creating a plurality of computing object logical groups of a subject of the plurality of computing objects having substantially same computing object properties. The lookup matrix provides answers whether each member of a selected computing object logical group can be transferred to each member of a selected host logical group.

摘要： One embodiment is a method of transferring data from a computer system to a Universal Serial Bus (USB) device after a computer system crash where interrupts are masked, the method comprising: (a) detecting the computer system crash; (b) transferring at least a portion of the data to a USB driver for the USB device; (c) the USB driver transferring the portion of the data to a USB controller driver for a USB controller for the USB device; (d) the USB controller driver causing the USB controller to transfer the portion of the data to the USB device; (e) polling the USB controller to determine whether the data transfer was completed; and (f) if the data transfer was completed, providing a notification to the computer system. Another embodiment is a method of transferring data from a Universal Serial Bus (USB) device to a computer system after a computer system crash where interrupts are masked, the method comprising: (a) detecting the computer system crash; (b) identifying a USB device used to communicate data to the computer system; (c) polling a USB controller for the identified USB device to determine whether new input has been received; (d) if so, obtaining the new input; and (e) transferring the new output to the computer system for further processing.
