Abstract: Isolating resources of a virtual machine (VM) guest from a host operating system. A computer system receives an acceptance request from a guest partition corresponding to an isolated VM. The acceptance request identifies a guest memory page that is mapped into a guest physical address space of the guest partition, and a memory page visibility class. The computer system determines whether a physical memory page that is mapped to the guest memory page meets the memory page visibility class. The computer system sets a page acceptance indication for the guest memory page from an unaccepted state to an accepted state based on the physical memory page meeting the memory page visibility class.

Abstract: Provided is an adjustable split thrust ring and a drilling system including the same. The adjustable split thrust ring, in one embodiment, includes a downhole split ring including two or more separate downhole pieces, the two or more separate downhole pieces fitting together to form a substantially circular downhole shoulder surrounding a substantially circular driveshaft. The adjustable split thrust ring further includes an uphole split ring positionable proximate the downhole split ring and including two or more separate uphole pieces, the two or more separate uphole pieces fitting together to form a substantially circular uphole shoulder surrounding the substantially circular driveshaft. In this embodiment, the substantially circular downhole shoulder and the substantially circular uphole shoulder are movable relative to one another to adjust to fit a groove in a driveshaft that they are configured to sit.

Abstract: A wellbore assembly is provided that can include a first motor housing assembly member and a second motor housing assembly member that can bend relative to the first motor housing assembly at a bend location. The assembly can also include a first inclinometer positioned on assembly side of the bend location to determine a first inclination and a second inclinometer positioned on a second side of the bend location to determine a second inclination. Based on the first and second inclinations, the amount of bend or bend direction of the second motor housing assembly member relative to the first motor housing assembly member can be determined.

Abstract: A wellbore assembly is provided that can include a first motor housing assembly member and a second motor housing assembly member that can bend relative to the first motor housing assembly at a bend location. The assembly can also include a magnet positioned to emit a magnetic field. A sensor can be magnetically coupled with the magnet and positioned to detect the strength of the magnetic field emitted by the magnet. Based on the strength of the magnetic field detected by the sensor, the amount of bend or bend direction of the second motor housing assembly member relative to the first motor housing assembly member can be determined.

Abstract: A bend angle sensing assembly for determining a downhole bend angle of a downhole adjustable bent housing. The bend angle sensing assembly includes a flow diverter having a plurality of diverter apertures for receiving drilling fluid, the flow diverter orientable to a plurality of diverter configurations in dependence on the bend angle of the associated downhole adjustable bent housing. Each of the plurality of diverter configurations have one or more of the plurality of diverter apertures opening or closing to form a corresponding flow path configuration, each flow path configuration having a different flow area whereby the pressure of the drilling fluid changes for each flow path configuration. Additionally, a pressure sensor is communicatively coupled to the drilling fluid.

Abstract: A wellbore assembly is provided that can include a first motor housing assembly member and a second motor housing assembly member that can bend relative to the first motor housing assembly at a bend location. The assembly can also include a strain gauge positioned on a first side of the bend location to determine an amount of bend of the second motor housing assembly member relative to the first motor housing assembly member by determining a strain. Based on the strain, the amount of bend or bend direction of the second motor housing assembly member relative to the first motor housing assembly member can be determined.
