Abstract: The present disclosure relates to providing availability of passthrough devices configured on VCIs according to one or more embodiments of the present disclosure. One method includes receiving a notification of a failure associated with a passthrough device configured on a VCI, communicating, to the VCI, a simulation of a surprise hot removal of the device from the VCI, resetting the device, communicating, to the VCI, a simulation of a surprise hot add of the device to the VCI, and hot adding the device to the VCI.

Abstract: Techniques for migrating virtual machines (VMs) in the presence of uncorrectable memory errors are provided. According to one set of embodiments, a source host hypervisor of a source host system can determine, for each guest memory page of a VM to be migrated from the source host system to a destination host system, whether the guest memory page is impacted by an uncorrectable memory error in a byte-addressable memory of the source host system. If the source host hypervisor determines that the guest memory page is impacted, the source host hypervisor can transmit a data packet to a destination host hypervisor of the destination host system that includes error metadata identifying the guest memory page as being corrupted. Alternatively, if the source host hypervisor determines that the guest memory page is not impacted, the source host hypervisor can attempt to read the guest memory page from the byte-addressable memory in a memory exception-safe manner.

Abstract: An automated end-to-end analysis of customer service requests is disclosed. A core dump is received, wherein the core dump corresponds to a customer service request regarding a crash of a computer system. A processor automatically analyzes the core dump to determine if a pcpu lockup of the computer system is due to a software issue. Provided the pcpu lockup of the computer system is due to the software issue, the processor determines which thread is a culprit thread responsible for the pcpu lockup of the computer system.

Abstract: A computer-implemented method for providing crash results for a computer system on a graphical user interface is disclosed. A component access control feature is displayed on a graphic user interface. The component access control feature enables a user to select a component and view crash results pertaining to the component. A graphical representation for display on the graphic user interface is generated. The graphical representation includes at least a portion of a signature back trace corresponding to a crash associated with the component.

Abstract: A computer-implemented method for monitoring a crash analysis system is disclosed. Log messages are accessed pertaining to the operation of a crash analysis system for analyzing a core dump. The log messages are analyzed, at a processor, in order to generate operation results data. A graphic user interface for display on a computer is generated. The graphic user interface includes a graphical representation of the operation results data.
