CPU REGISTER ASSISTED VIRTUAL MACHINE SCREENSHOT CAPTURE TIMING APPARATUSES, METHODS AND SYSTEMS

摘要

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.

主权项

1. A method for verifying a status of an operating system running on a virtual machine, the method comprising:
obtaining, by a server, a plurality of virtual central processing unit (CPU) register values associated with at least one virtual CPU register of a virtual CPU on a hypervisor, the hypervisor providing virtualization services to the virtual machine; determining, based at least in part on the plurality of virtual CPU register values, the status of the operating system; and acquiring an output of the virtual machine so as to verify the status of the operating system.
