Abstract: Embodiments of the disclosure enable exit-less movement of guest memory assigned to a device in a virtualized environment. An example method comprises detecting, by a processing device of a host computer system, an event triggering a move/copy of a memory page residing at a first memory location that is mapped to a virtual address space of a virtual machine being hosted by the host computer system. Thereafter, the first memory location is un-mapped from the virtual address space of the virtual machine. Responsive to determining that a DMA write indicator associated with a hardware device assigned to the virtual machine indicates that a DMA write operation is not in progress, the memory page is moved from the first memory location to a second memory location. Then, the second memory location is mapped into the virtual address space of the virtual machine for use by an input/output memory management unit.

Abstract: Disclosed is a method for creating and reading a contiguous file in an extensible file system. During the creation of a file on the storage media, the file system format check the bitmap to determine if there are areas of free space on the media that would permit the storage of the file in a contiguous manner.

Further, an associated entry for the file in the directory entry is updated or created to indicate that the file is a contiguous file and also provides basic parameters necessary to read the file without resorting to accessing the file allocation table.
