Abstract: Examples are provided for a device comprising a processor to create a volume in a memory. The volume may be based on an operating system (OS) image. The processor may: attach the OS image to a virtual machine, and attach the volume to the virtual machine as a disk of the virtual machine. The virtual machine may: boot using the attached OS image, determine a version of the attached OS image, determine a set of advanced configuration power management interface (ACPI) tables for different permutations of hardware, store the set of ACPI tables corresponding to the hardware permutations in the attached volume, and modify the attached volume to create a modified volume based on the set of ACPI tables. The modified volume is bootable by the different permutations of hardware. The processor may further store the modified volume on the storage device.

Abstract: Some examples provide a system including neighboring computing devices comprising a deployed operating system (OS) volumes, and respective neighboring bit tables corresponding to the deployed OS volumes. The system may include a target computing device comprising a target operating system (OS) volume. The target computing device may determine a target bit table corresponding to the target OS volume. Each bit in the target bit table indicates whether the data block of the target OS volume differs relative to a base OS volume. The target computing device may determine, based on bit tables, a first set of data blocks that are identical to a second set of data blocks of the deployed OS volumes. The target computing device may receive the least one data block in the second set of data blocks from the neighboring computing devices, and assemble the target OS.
