description The present application relates to the technical field of industrial Internet operating systems, and particularly, to an exception handling method, apparatus and system in a virtual operating environment, which are used for solving the problem that Guest OS that is operated in a virtual environment has poor robustness. The exception handling method in a virtual operating environment provided in the embodiment of the present invention comprises: monitoring an exception that is generated by Guest OS operated on a virtual machine; and if it is determined according to acquired context information of the exception that the exception is generated due to an out-of-limit operation performed by Guest OS on a kernel code whose operation permission is limited in the virtual machine, rejecting the out-of-limit operation performed on the kernel code by Guest OS, wherein, for a key kernel code in the virtual machine, the operation permission of Guest OS for the kernel code can be extended, that is, one more layer of securi
