Abstract
A method includes detecting a triggering event at a hypervisor, where the hypervisor is executed by a computing node. The method also includes capturing, from a memory device of the computing node using the hypervisor, one or more images of a basic input/output system (BIOS) of the computing node and/or a firmware of the computing node. The method further includes analyzing the one or more images to detect a problem with the computing node and taking at least one action in response to detecting the problem with the computing node. The one or more images are obtained by the hypervisor directly from the memory device.
