Abstract

APPARATUSES, METHODS AND SYSTEMS FOR DETERMINING A VIRTUAL MACHINE STATE (“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.

First claim

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.
