Abstract
The CPU REGISTER ASSISTED VIRTUAL MACHINE SCREENSHOT CAPTURE TIMING APPARATUSES, METHODS AND SYSTEMS (“CRV”) transforms register retrieval requests, via CRV components, into boot success messages and screenshot capture command invocation outputs. A method comprises determining when to capture a screenshot of a virtual machine's display output by observing the values of a virtual CPU's registers, or the entropy of the virtual CPU's register values, obtained from a hypervisor in communication with the virtual machine's virtual CPU. The method further comprises determining when the virtual machine is at a boot success state and capturing a screenshot of the virtual machine display output.
