摘要： In one approach, a method is described of generating an interface for an operating system kernel. The method calls for creating an input file, where the input file includes a node structure for the interface. A kernel component of the interface is generated from the input file. A user space component of the interface is also generated from the input file.

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： Hardware virtualization support is used to isolate kernel extensions. A kernel and various kernel extensions are executed in a plurality of hardware protection domains. Each hardware protection domain defines computer resource privileges allowed to code executing in that hardware protection domain. Kernel extensions execute with appropriate computer resource privileges to complete tasks without comprising the stability of the computer system.

摘要： A computer has a hardware memory arranged into portions that are separately addressable using first identifiers, which are represented using a first number of address bits. A subsystem that is able to address a second space of the hardware memory using second identifiers initiates I/O requests directed to a device that is able to address a different, first memory space using first identifiers, which are represented using a second number of address bits. The second identifiers are initially mapped into the second memory space, but for any I/O request that meets a remapping criterion, the corresponding second identifier is remapped to one of the first identifiers that identifies a portion of the memory in the first memory space. The second space is different from the first space and the second number of address bits is greater less than the first number of address bits.

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.
